    The file can contain a list such as:

v9.48f for Windows (August 19th, 2022):

  • The Sharepoint library list is now sorted alphabetically, and the window can be enlarged.
  • Removes a bogus warning message “The timer is currently running this profile”, and fixes background progress being shown for the wrong profile (both could occur only if the scheduler is not set to start profiles in parallel).

v9.48e for Windows (August 19th, 2022):

  • Fixes warnings like “Releasing orphaned CS” in the log files, when a user account is specified in the profile (via “Access Local Files As User”).

v9.48d for Windows (August 19th, 2022):

  • Includes a SmartTracking improvement where the creation date will now be used to detect if a folder or file has recently been added and should not be deleted, even if the same version was deleted from the other side.
  • Minor improvements.

v9.48c for Windows (August 16th, 2022):

  • The parent folder names for user folders can now be configured on the Program Settings dialog, tab sheet Logs. When synchronizing multiple user profiles between servers, Syncovery uses this to recognize the user folders and avoid trying to detect moved files between different users.
  • SmartTracking details will now always be logged for deletions and conflicts.

v9.48b for Windows (August 11th, 2022):

  • The watchdog mechanism will no longer kill threads. It will only report hanging jobs and free mutexes so that hanging jobs can be run another time.

v9.47 build 387 for Windows (May 5th, 2022):

  • Implements the SmartTracking feature “Rename on one side and copy both versions” for conflicting files when one side is FTP/WebDAV etc. or a cloud protocol.
  • Fixes a bug where uploading files to DropBox on the left side of the profile would use the current timestamp as modification date.

v9.47k (build 386) for Windows (April 27th, 2022):

  • Fixes a problem where NTFS security settings were sometimes not processed.

v9.47j (build 385) for Windows (April 25th, 2022):

  • Solves a problem that occurred on a customer’s computer where the Program Settings dialog opened with an error message.

v9.47f for macOS and Linux/NAS (March 31st, 2022):

  • Includes improvements from the Windows version.
  • macOS only: fixes one more possible segmentation fault/AV.

v9.47f for Windows (March 30th, 2022):

  • Can detect and exit endless loops when downloading a changes-based listing from DropBox. There was one case where the DropBox server always claimed that there are more changes to download even though there were none.
  • Fixes access to the global variables of type UnicodeString from PascalScript. These had been broken since v9.47 due to internal changes.

v9.47e for Windows and macOS (March 30th, 2022, Mac: Intel 64-bit only):

  • Fixes the checkmark “Automatically resume” from getting unchecked when the job runs if an intermediate copying location is used.
  • Fixes an error preventing the Background Scheduler on macOS from starting on some systems (Intel only).

v9.47d for macOS (March 29th, 2022, Intel 64-bit only):

  • The option to skip the VolRefNum checks will now also prevent messages like “Volume unmount detected” due to unexpected volume reference numbers while the job copies files.

v9.47c for Windows (March 23rd, 2022):

  • Adds an option on the Program Settings dialog, tab sheet Misc: “Delete left-over (remote) listing files older than X minutes from the temp folder”.
  • Includes a new Remote Service v9.47 with a new option on the tab sheet “Remote Listing and MD5 Checksums”: “Delete left-over listing files older than X minutes”.
  • Fixes an issue where large uploads to B2 could sometimes fail due to an expired authentication token.

v9.47b for Windows (March 19th, 2022):

  • Adds checkmark “Create Profile Change Logs” to the Program Settings dialog, tab sheet Logs.
  • Avoids re-scanning individual folders when mirroring from Sharepoint directly to S3 (and similar combinations)
  • Allows downloading from FTP to long paths of over 260 characters. This previously worked only with two of the four FTP libraries.
  • Scheduled jobs which need cloud authorization via web browser will no longer re-run and re-try the authorization indefinitely, because it requires user interaction.
  • Profiles which are currently running can no longer be deleted, because then they would be invisible and unstoppable.
  • Fixes an error message trying to write to C:\ProgramData\Syncovery\JobsRunInMainProcess.txt when jobs are run in Background with Preview.

v9.47a for macOS and Linux (March 21st, 2022):

  • Stability fixes and various improvements on macOS.
  • macOS: adds checkmark “Create Profile Change Logs” to the Program Settings dialog, tab sheet Logs.
  • Adds “Skip Files Whose Size is Changing” to the web GUI, tab sheet Files->More.
  • Includes recent improvements and fixes from the Windows version.

v9.47a for Windows (March 19th, 2022):

  • Fixes a threading issue while scanning folders, which could, in extreme situations, cause errors or incorrect comparisons and incorrect copying. The problem usually surfaced only when more than 5 scanning threads were used and a lot of folders were scanned.
  • Double-checks the contents of the profile’s base folder on DropBox, because sometimes DropBox may not list all items with the changes based listing.
  • Additional stability improvements.

v9.47 for Windows (March 15th, 2022):

  • Generic stability improvements related to multithreading.
  • Improved speed displaying the profile selection tree in Wizard mode.
  • Double-clicking between column headers in the Profile Overview and the Sync Preview will now reset column widths to the defaults.
  • Fixes zipping files with alternate data streams when the source is a volume shadow.
  • Fixes background scheduler behavior after Windows sleep has been detected.
  • Contains a Monitoring Tool bug fix, which sometimes showed “Invalid status file”.
  • Contains a configuration file speed-up in some situations.
  • Miscellaneous internal optimizations.

v9.46p for macOS (March 4th, 2022):

  • Recursive SSH listings now use UTC timestamps when connecting to another Mac or BSD system. This fixes timezone offset problems. Linux SSH/SFTP servers were not affected.
  • Includes recent improvements from the Windows version.

v9.46o for Windows (March 2nd, 2022):

  • Contains the new Syncovery Remote Service v9.46, where the “Apply” button no longer restarts the service. New settings can be applied on the fly. Also, the service can now easily be stopped while it is processing listings and will report appropriate status messages to the control panel (such as stopping/stopped).
  • Contains an rsync listing parsing fix.

v9.46n for Windows (February 28th, 2022):

  • SmartTracking can now be combined with the “Flat Right Side” option.

v9.46m for Windows (February 22th, 2022):

  • No longer complains if you are copying from one cloud account to another and the profile’s base path look identical (but are different accounts).

v9.46k for Windows and Linux (February 18th/19th, 2022):

  • The Graph protocol will now show all Office365/Sharepoint groups that the authenticated user is a member of and no longer requires Admin priviliges to list groups.
  • Adds HTML help pages to the Linux web GUI.
  • Fixes authentication with Amazon GovCloud.

v9.46j for macOS (February 17th, 2022):

  • Fixes rare hangs when disconnecting from FTP servers.


  • Unpublished internal test releases

v9.46g for Windows and macOS (February 15th, 2022):

  • The option “Flat Right Side” is now compatible with subfolder selections that do not include the base folder. The right-hand side base folder will be read anyway, because the right side is flat.
  • Fixes checksum errors when uploading large files to Amazon Glacier directly (not via S3).
  • Includes the plain HTTP protocol for the first time on macOS, so Mac users can now download from simple HTML web sites and public DropBox links too.

v9.46f for Windows (February 13th, 2022):

  • Switches to TGPuttLib automatically if SecureBlackBox can’t load the private key for SFTP connections.
  • Now downloads updates via web browser if the directly downloaded setup program fails to run.
  • Fixes the button “Forget cloud access tokens” which recently deleted cloud tokens from Syncovery.ini only, although they are now in Vault.ini.

v9.46e for Windows (February 11th, 2022):

  • The new download feature from Dropbox public links has been improved further, and a possible socket error has been fixed.
  • FTP Retries can now be set to 0, in which case inaccessible subfolders are quickly skipped without any reconnection attempts.
  • The first FTP retry will no longer force a reconnection, it will just check the connection
    (so FTP retries set to 1 is also efficient if there are many inaccessible subfolders that need to be skipped)
  • Monitoring Tool first column width increased
  • GMail and Office 365 buttons fixed on SMTP server details dialog for email notifications
  • Works around possible SSL certificate validation problems with some Google Cloud Storage buckets by switching to WinInet automatically.
  • Tested with FE File Explorer FTP Server on iPhone

v9.46d for Windows (February 8th, 2022):

  • Fixes a problem where in a redundant installation of Syncovery on two machines, the second machine would not take over despite the scheduler being stopped on the first.

v9.46c for Windows (February 8th, 2022):

  • Fixes a bug in v9.46a/b causing profiles not to enter the copying phase if they use only one copying thread and at least one side is an Internet Protocol.

v9.46b for Windows (February 7th, 2022):

  • Fixes an error in v9.46a (only): “CopierState<>csGotJob” that could lead to “Waiting for file access” when a profile was set to copy only one file in parallel.

v9.46a for Windows (February 6th, 2022):

  • Fixes a bug introduced in v9.45a, which could occasionally cause some files to be skipped during the copying phase in high speed copying scenarios with many files and more than three copying threads.
  • Fixes the copying rate display (in MB/sec) getting stuck at the highest value sometimes.
  • Some bugs have been fixed related to changing a base path in the Sync Preview to achieve a different copying destination from the folder used during scanning.

v9.46 for Windows (February 4th, 2022):

  • This update completes the new feature to download from DropBox public links. They now work with subfolders and show file details, including size and modification date/time. You can just paste the whole link in the left or right base paths and do not need to change any other settings.
  • The command line tool SyncoveryCL now handles Ctrl-C better and finishes jobs rather than just exiting.

v9.45m for Windows (February 2nd, 2022):

  • Continuous/never-ending profile runs only: if deletions are disabled due to an exception or other error or listing discrepancy, they will now be reinstated on the next continuous run rather than remaining disabled until the profile is completely stopped and restarted.
  • Wasabi France region added to list of S3 providers.
  • Can download from DropBox public links if you remove the ?dl=0 at the end of the URL and choose the HTTP protocol.

v9.45l for Windows, Linux and Mac (January 31st, 2022):

  • Fixes a bug that was introduced in 9.45i causing recursive listings to fail and use excessive memory if the FTP server included . and .. entries in the listing.
  • Improved handling of the next full run time for real-time profiles that also have scheduled full runs.
  • Web GUI improvements.

v9.45k for Linux and Mac (January 30th, 2022):

  • Includes recent improvements from the Windows version.
  • Fixes a possible hang in the real-time module (also responsible for the option “run when drive is available”).

v9.45k for Windows (January 29th, 2022):

  • Implements the speed limit for uploading compressed packages.
  • Uses a bit less memory when processing large recursive FTP listings.
  • Can now upload empty files to Azure BLOB storage.
  • The Archive Flag filter is no longer applied to Internet Protocols, as these don’t have an archive flag.

v9.45j for Windows (January 29th, 2022):

  • Fixes Combo Edition registration codes not being recognized in 9.45i.

v9.45i for Windows (January 28th, 2022):

  • Fixes a few issues with recursive FTP listings, especially from Synology NAS devices.
  • Fixes a problem with the destination file list cache when used with FTP servers, where older files don’t get a reported time of day in the listing. The cache database didn’t remember this status and reported the time as midnight UTC, which could cause files to be re-copied every time the job runs.
  • Block level copying (esp. uploading to SFTP) can now tolerate if the source file becomes larger during the copy.

v9.45g for Linux (January 25th, 2022):

  • First release of 9.4 with new settings encryption (see new options on the Program Settings dialog).
  • Fixes the integrated SMB protocol setting incorrect modification dates when SMB is the destination of a copy. Incorrect dates will automatically be corrected as Syncovery sees them when scanning folders.
  • Various web GUI improvements (especially for the FTP protocol).
  • Now accepts all Combo Edition registration codes, not just the Linux-specific code.
  • A status report with detailed thread checkpoints is created when the user puts a file called “wantstatus” in the program folder or in /tmp. The new Guardian v1.60 will be able to trigger and show this report.

v9.45f for Windows and 9.39z for Linux (January 23rd, 2022):

  • These updates fix a problem where in some cases, zip files with only metadata rather than the actual content were created. It happened if Syncovery had downloaded the source file via a protocol rather than accessing it locally, and was also configured to save metadata or alternate data streams in the archive. In another case, it could happen if filename encryption was chosen and metadata or alternate data streams were also added.
  • A similar bug could occur with Sz files. These could be empty if the source file was downloaded via FTP library 4 on Windows or 1 on Linux.

v9.45e for Windows (January 22nd, 2022):

  • Fixes a passive mode connection issue with FTP library #2 when connecting to an FTP server behind a NAT router.
  • Automatically chooses FTP library #2 if there are connection problems due to FileZilla FTP Server’s “TLS session of data connection has not resumed” error.

v9.45d for macOS (January 19th, 2022):

  • M1 only: updates OpenSSL to v1.1.1m, and fixes buttons and other text appearing in German in the English version.
  • Intel 64-bit only: fixes a dylib issue causing the Mega protocol not to work in v9.45b/c.

v9.45d for Windows (January 18th, 2022):

  • When checking an individual file’s size and/or timestamp via FTP, Syncovery will no longer fall back to a regular (slow) FTP listing if an error occurs when trying SIZE/MLST/MDTM. Instead, the faster FTP commands are retried with reconnection attempts as necessary.
  • Syncovery will no longer try to adjust folder timestamps via FTP when connected to FileZilla Server (which doesn’t support it).
  • Fixes large uploads to Sharepoint/OneDrive failing if the authorization token has expired. Syncovery will refresh tokens as necessary, as with all other operations.

v9.45b/c for macOS and Windows (January 17th, 2022):

  • First macOS release of Syncovery 9.4x with the new settings encryption features and an updated TGPuttyLib version.
  • Fixes a bug where the copying rate calculation would stop and show the same rate for a longer time during the copying phase.
  • The “Check for update” feature will show detailed error message in the future, if the connection to the update server fails.
  • 9.45c fixes a Range Check Error preventing the program to open on M1 Macs if “Extreme Debug Logs” was enabled. It also turns Extreme Debug Logging off automatically after 24 hours.
  • 9.45c for Windows adds more detailed logging when copying a compressed package to the destination.

v9.45a for Windows (January 15th, 2022):

  • Copying many small files between fast disks (such as local SDDs) is now around three times faster.
  • Uploading large files to OneDrive or Sharepoint now handles server errors better and will now always succeed and resume correctly.
  • Profiles using the “never-ending profile run” option no longer log out and back in to (S)FTP servers for the main thread. Since v9.39, Syncovery hadn’t keep the connection open, but now it does again.
  • Fixes possible delays after saving a profile.
  • The question whether to create the destination folder (if it doesn’t exist yet) can now be skipped.
  • SyncoveryCL.exe and SyncoveryService.exe will now correctly recognize if Syncovery.ini is in the same folder, i.e. in a portable folder on a flash drive, and read the license and profiles from that Syncovery.ini file.

v9.45 for Windows (January 11th, 2022):

  • Adds two checkmarks “Lock” on the Program Settings dialog, to the Path for logging and the Path for SmartTracking and Caching Databases. These prevent unexpected changes to these paths. If locked, Syncovery will not revert to default folder locations in case of an error.
  • In case of database problems, Syncovery will now automatically create a new database with a different name as a fallback, rather than erroring out and not being able to run the profile.
  • Fixes an internal locking bug that could lead to databases being incorrectly seen as locked.

v9.44d for Windows (January 10th, 2022):

  • Fixes some dialog / button layout issues.
  • Fixes “ChkNm3” hangs, which could occur when Syncovery was analyzing an NTFS Reparse Point. The new version no longer tries to open unknown reparse point types.
  • Syncovery may have asked for an archive password when restoring, even though the password was saved in the profile. This has been fixed.
  • The error message “Cannot rename” is now more detailed (if it happens at all). It can occur when an INI file can’t be saved because other Syncovery processes are locking it.
  • Additional minor improvements.

v9.44c for Windows (January 7th, 2022):

  • Adds a new checkmark on the Program Settings dialog, tab sheet Cloud: Buffer Complete Parts When Uploading To S3. This may help increasing upload speeds, but uses more memory.
  • Optimized to work with FileZilla FTP Server – at least FTP libraries 2 and 3 should work.
  • FTP Library 2 now supports TLS 1.3 and TLS session resuming.
  • S3 protocol: fixes occasional bogus file verification errors (when using Binary Comparison of Existing Files) due to MD5 checksums that don’t match. The reason is that S3 doesn’t report MD5 checksums on large files that have been uploaded in multiple parts. Syncovery can only verify these files be downloading them.
  • The 32-bit Setup programs have been signed with our new code signing certificate, and Windows might not trust it yet – please override any warnings. If you want to help us get this new certificate be recognized by Microsoft’s SmartScreen, please download the 32-bit edition and override any warnings (you can cancel the installer once it shows up).

v9.44b for Windows (January 5th, 2022):

  • Improves upload speed of large files to Amazon S3 by allowing each thread to open the source file independently, rather than having just one file handle whose usage is limited due to thread concurrency.
  • Continuous profiles (“never-ending profile run”) will no longer close and re-open the database on every run (if a database is used).
  • Free disk space checks can now be disabled entirely on the Program Settings dialog, tab sheet “Memory”.
  • The Auto-Resume mode with temporary filenames can now be used when uploading to PCloud, because PCloud may put incomplete, interrupted uploads in your cloud storage. The temporary filenames will help prevent confusing incomplete files with real ones, and cause Syncovery to re-upload such files on the next profile run.
  • Binary comparison while building the file list now works with storages like PCloud, where the files’ modification timestamps are lost upon upload. Despite having a newer timestamp, Syncovery will do the Binary comparison if the profile’s copying direction is only “upload” and not two-way.
  • The TLS version selection on the Internet Protocol Settings dialog has been updated to allow only TLS v1.1+, 1.2+, and 1.3+. The GUI is slightly ahead of the actual implementation of most protocols here, because TLS 1.3 is not supported by most protocols yet. This will be added one by one in the near future.

v9.44a for Windows (January 2nd, 2022):

  • Includes SzArchiver v0.82 but no longer places an SzArchiver icon on the desktop.
  • No longer writes log file related debugging codes to LastLogFiles.ini.
  • Additional internal optimizations.

v9.44 for Windows (January 1st, 2022):

  • Now includes the SzArchiver tool to open Sz files.
  • The scheduler was optimized to handle many profiles and can now launch up to 8 profiles per second.
  • Fixes a problem with the “Flat Right Side” option where in unattended or scheduled runs, some files might be re-copied every time.
  • Fixes a leak where Sz files would sometimes contain the original file name in clear text even if filename encryption was used.
  • Additional optimizations and bug fixes.
  • Contains an updated FTP library #2 and also minor changes in FTP library #3.

v9.43b for Windows (December 27th, 2021):

  • Fixes incorrect (S)FTP upload progress reporting when a transfer of a large file is interrupted and resumed more than once during a profile run.
  • Fixes various resuming bugs with uploads and downloads of FTP transfers.

v9.43a for Windows (December 23rd, 2021):

  • Adds a new PascalScriptHook called OnNormalizeFilename which can be used to normalize filenames before Syncovery compares them.
  • Fixes a problem where sometimes invalid timestamps were shown in the “Last Run” column.

v9.43 for Windows (December 19th, 2021):

  • Completely rewritten Timezone Detection for FTP servers, without uploading any test files and taking almost no time. Optimized use of FTP commands such as MLST and MDTM. Only with FTP servers that do not support any of these commands, Syncovery will still use the old Timezone Detection (which is rare).
  • Syncovery no longer does any Timezone Detection for SFTP servers, because the SFTP protocol is supposed to be timezone independent and always use UTC times.
  • Fixes non-English characters such as Umlauts being lost in the registration name and Email sender, in versions 9.40-9.42.
  • Email sending with TLS and Backblaze B2 connection now work on Windows XP again.
  • Fixes some small temporary files like TGTEMP.$$$ not being cleaned up, when working with a Remote Listing via Internet Protocol.
  • Includes a compatibility fix with FileZilla FTP Server. When using FTP library 3 in Syncovery, an empty folder seletion box could be shown. An empty listing may also have been generated when running a profile, depending on the FTP Listing Command.
  • The OnIncludeItem PascalScript hook is now also called for real-time folders with changes.
  • Fixes Syncovery occasionally thinking the settings are read-only.
  • Improved tray icon for low resolution monitors.
  • Additional improvements and bug fixes.

v9.42a for Windows (December 16th, 2021):

  • Fixes an IntOverflow error that occurred on one customer’s server when the scheduler tried to determine the next run time for a profile.
  • Works with AWS PrivateLink bucket URLs ending in vpce.amazonaws.com

v9.42 for Windows (December 15th, 2021):

  • Right-clicking on a profile group now shows group-specific menu items again (they were missing in v9.40/9.41).
  • Adds a checkmark and feature “Via Internet Protocols Too” under Files->More (scroll down), related to the feature “Check Destination File (Again) During Copying Phase”. This is especially useful when “And Compare File Details (Again)” is also checked. It avoids incorrect copying directions due to file changes between the folder scanning phase and the copying phase. Previously, this feature was implemented only for copying locally or via LAN (UNC Paths).
  • When using “a single, never-ending profile run”, previous copying results will now be replaced by “Nothing to do”, so that error messages don’t stay in the progress report for too long.
  • Adds the PascalScript function “FileExistsMatching” which allows you to check for a path with wildcards in the file name.
  • “Verify destination file size after transfer” will no longer throw an error if the uploaded file is already gone when the check is made. It will only check for incorrect sizes, and ignore if the file size cannot be detected. The reason is that many customers use Syncovery to move files to a server that immediately removes incoming files and sends them to further processing.
  • Fixes the settings encryption reappearing every time you open Syncovery if you choose to stick with legacy encryption.
  • Fixes garbled configuration entries when using the “Email” protocol as one side of the sync. These were caused by the new encryption method in v9.40.
  • Now uses MIME types from the Windows registry for uploading to cloud services.
  • Allows to use variables in email subjects and body for emails sent with the “Email” protocol as sync destination.
  • Various additional improvements.

v9.41b for Windows (December 13th, 2021):

  • Fixes an issue since v9.40 where the background scheduler would not automatically start with Windows on some systems – if an “Idle time after startup” was configured, and the scheduler was not installed as a service.

v9.41a for Windows (December 12th, 2021):

  • Cloud tokens are now saved in Vault.ini.
  • Automatically fixes permission problems with ini files.
  • The new credentials encryption settings can now be accessed even if Syncovery was started with the /INI= command line parameter.
  • Additional improvements.

v9.41 for Windows (December 11th, 2021):

  • To protect the integrity of Syncovery.ini, all transient data is now written to separate ini files. Syncovery.ini is now almost exclusively written to when the user changes settings.

v9.40 for Windows (December 9th, 2021):

  • Provides new, safer encryption methods to store your passwords and credentials securely.
  • Passwords are now also stored encrypted in memory while Syncovery runs, so that a memory dump of the Syncovery process will not contain any passwords (except while a profile is being edited).
  • Shows profile counts on the Profile Overview. The total is shown in the status bar, and group counts are shown for each group.
  • Can now export profiles with credentials, even to CSV and XML files. The user has a choice between different encryption methods for the exported credentials. Plain text export is only available if the main config is password protected, and the user can prove that she/he knows the password by entering it.
  • Now internally saves credentials in separate fields, rather than as part of the profile base paths, such as ftp://username:password@server.url. Many code optimizations have been made related to this reorganization.
  • Separate command line parameters have been added to specify credentials for Internet Protocols: /LUSER=xyz, /RUSER=xyz, /LPASS=xyz, /RPASS=xyz.
  • Various additional improvements.

v9.39x for Windows (December 7th, 2021):

  • Fixes a GUI but since 9.39v where some GUI text was sometimes not shown (replace by ||||||).

v9.39w for Windows (December 2nd, 2021, German only):

  • Includes a workaround for a rare problem when downloading remote listings (made by the Syncovery Remote Service) via FTP/SFTP/WebDAV. Syncovery now overrides the checkmark “Verify destination file size after transfer” and skips the size check. The listing itself has checksums etc. so that this size check isn’t needed (and for some reason it failed on at least one customer server).

v9.39v for Windows (December 1st, 2021):

  • Adds additional Wasabi endpoint regions.
  • Allows to specify a default S3 region via a line in Syncovery.ini, such as:
  • When downloading via Internet Protocol, Syncovery used to un-hide hidden folders. This has been fixed.

v9.39u for Windows (November 28th, 2021):

  • Fixes a GUI bug in 9.39t where collapsed profile groups wouldn’t stay collapsed.

v9.39t for Windows (November 28th, 2021):

  • It is now possible to make new connections with Google Cloud Storage again, after the previous Syncovery version had reached a user limit.
  • Possible Google Cloud Storage upload/download bug fix.

v9.39s for Windows (November 28th, 2021):

  • Allows to specify the timout on the Execute before/after dialog box.
  • Fixes “Move Files Mode” with DropBox as destination.

v9.39r for macOS (November 23rd, 2021):

  • Adds a checkmark to skip the VolRefNum check on the “More” tab sheet of the Program Settings dialog.
  • Includes improvements from recent Windows and Linux updates.

v9.39r for Linux (November 22nd, 2021):

  • Complies with a new OAuth 2.0 syntax requirement for Box as a cloud storage provider.
  • Includes the new TGPuttyLib build 18 based in PuTTy v0.76 (Intel 64 bit version only).
  • Fixes a Range Check Error when using compressed Zip packages (with multiple files per zip).
  • Fixes a problem where jobs that use the “Move Files to Destination” mode with DropBox as destination could not delete the source files.

v9.39q for Windows (November 20th, 2021):

  • Fixes a problem where Exact Mirror profiles using Folder Masks would try to delete folders from the destination that don’t match the folder masks, if they don’t exist on the source side. These deletions would have normally failed, because the folders were not empty, but it’s cleaner to not try to delete them.
  • Adds additional capablities to Execute before/after; you can now specify the timeout in seconds and specify whether to continue anyway, if the command times out.

v9.39p for Windows (November 14th, 2021):

  • Default requirements for free memory (RAM) have been halved once more, so that only 1 GB of free RAM is expected when running a profile on a machine that has 16GB of RAM. On 8 GB, only 512MB are expected.
  • Stops trying to delete old timezone check files if the deletion fails. Timezone deletion file clean-up can be disabled with NoTimezoneCheckCheckFileDeletions=1 in Syncovery.ini.
  • A bug has been fixed when importig profiles or creating profiles via command line, where the order of the parameters sometimes made a difference (but should not).
  • Additional internal improvements.

v9.39o for Windows (November 9th, 2021):

  • Contains an updated TGPuttyLib with a final upload progress and buffering fix.

v9.39n for Mac (November 6th, 2021):

  • Fixes a bug in 9.39m that caused jobs to be split into parts of 100,000 entries.

v9.39m for Windows and macOS (November 3rd, 2021):

  • Windows only: fixes a bug in the TGPuttyLib SFTP Implementation that could cause incorrect transfer rates and timeout errors on large files due to excessive buffering.
  • Windows only: The free system memory requirements introduced in v9.39j can now be configured on the “Memory” tab sheet of the Program Settings dialog, and the default values have been halved.
  • No longer uses a default maximum memory usage of 8 GB per process, and the AbsMaxMemoryMB setting in Syncovery.ini is now ignored.
  • When using the checkmark “Skip Files Whose Size Is Changing”, Syncovery can now silently skip the files without an error in the profile results. To use this feature, choose “Ignore These Errors:” – “Access Denied Reading Files” on the File Access tab sheet in the profile.
  • Fixes a problem where sometimes one version of files too many is preserved when using the Sz compression format.
  • Avoids saving excessive logs in case of some types of failures or hangs.

v9.39k for Windows (November 1st, 2021):

  • Fixes a problem where longer running jobs that download from DropBox failed to refresh the authorization tokens.

v9.39j for macOS (October 30th, 2021):

  • Fixes an issue in v9.39i on Mac where even smaller jobs were split into parts unnecessarily.

v9.39j for Windows (October 27th, 2021):

  • Adds several precautionary measures to prevent jobs from running when system memory is scarce, or there is hardly any disk space for the profile’s database.
  • Prevents filling the log folder or C drive with “Syncovery Run Reports”.

v9.39i for macOS (October 27th, 2021):

  • Includes recent improvements from the Windows version.
  • When comparing file or folder attributes, it now ignores the Linux flags bit 0x0001, which sometimes can’t be mirrored.
  • Automatically creates SmartTracking database in user folder if an obsolete folder like in /Library is still specified, causing db creation errors.

v9.39i for Windows (October 24th, 2021):

  • Adds checkmark “Skip Files Whose Size Is Changing” under Files->More (scroll down to the end of the tab sheet).
  • Adds CRC32 functions to PascalScript and a sample script to shorten long file names.

v9.39h for Windows (October 20th, 2021):

  • Improves detection of completed profiles in order to avoid the message “Not starting job because …”.

v9.39g for Windows (October 19th, 2021):

  • Fixes CPU usage and too short delays when using jobs with “never-ending profile runs”.
  • Will now split jobs based on memory usage in addition to the number of entries, rather than stopping a job if the max. memory usage is exceeded.
  • It is now possible to compare filenames with different extensions and only mirror moves and deletions, as requested here.

v9.39f for Linux (October 11th, 2021):

  • Fixes web GUI stability issues (such as not loading or hanging).

v9.39f for Windows (October 7th, 2021):

  • Adds a new checkmark on the Move Settings dialog (for the Move Files to Destination mode):
    Delete Files from the Source Side Which Are Excluded By Masks
    (if they prevent removal of folders from the source side).
  • Now allows 0 seconds minimum pause between continuous profile runs.
  • Fixes an error message in the web GUI preventing editing of profiles.

v9.39e for Linux (October 7th, 2021):

  • Comptibility fix with Storadera (Syncovery did not recognize their MD5 checksums).
  • Includes recent additions and fixes from the Windows version.

v9.39e for macOS and Windows (October 6th, 2021):

  • When “Cache Destination File List” is used, and a file that should be moved no longer exists, Syncovery now updates the cache database – so that is won’t attempted to move the file again the next time the job runs.
  • Progress reporting fixes for compressed package copying.
  • Avoids useless retries when copying an Sz package to cloud servers fails because source files have changed during the process.
  • On MacOS, FTP library 2 will now use newer OpenSSL versions (like FTP library 1).

v9.39d for Windows (October 4th, 2021):

  • Adds the PascalScript function SaveProfileSettings.
  • Allows random subfolder remapping, i.e. the subfolder structure on the two sides can be completely different. The mapping must be provided in form of a mapping file (csv). Details are available on request.
  • Stops trying to copy Alternate Data Streams if the destination system doesn’t support them (such as exFAT).

v9.39c for Windows (October 3rd, 2021):

  • Adds an option to specify the maximum number of files to delete under Safety->Unattended in each profile. This number will default to 1,000 for new profiles and to 10,000 for existing profiles. If there are more files to delete, the deletions will be disabled.
  • Adds a new setting to the Program Settings dialog, tab sheet Misc: “Protect incompletely copied files – even if resuming fails, never restart from 0 or delete the incomplete file”. This option will also cause all profiles to use “Automatically resume (copy with temporay filenames, keep incomplete files when stopped).
  • Adds new settings to the Program Settings dialog, tab sheet Advanced: “Lifespan of a profil execution process” and “Flush file buffers during copy”.
  • Contains a new ETA algorithm.
  • Resuming improvements, will now less readily delete incomplete files if resuming fails.
  • Fixes the S3 option “make files publicly available” becoming unchecked when going back into the dialog.
  • Fixes the AWS V4 Signature problem in 9.39b
  • Fixes progress reporting sometimes missing (and the job appearing to hang) when uploading a compressed package (with multiple files per archive).
  • Fixes a possible freeze when right clicking on a profile that uses volume labels in paths.
  • Additional fixes and improvements.

v9.39b for Windows (September 25th, 2021):

  • This version was temporarily removed from the downloads because the OpenSSL update broke AWS V4 Signature Calculation.
  • The OpenSSL libraries have been updated to v1.1.1l.
  • The default FTP library #3 now finally uses OpenSSL v1.1.1 too.
  • When threads are terminated due to apparent hangs or timeouts, the incident is now logged to TerminatedThreads.log in the same folder as Syncovery.ini.
  • The scheduler now maintains a list of profiles that it runs in the main process, rather than additional profile runner processes. The list is saved to the file JobsRunInMainProcess.txt in the same folder as Syncovery.ini.
  • When getting a drive’s volume label has caused a hang in the past, it won’t be retried for two days, and a cached result from the last successful volume label check is used instead.
  • Fixes two quite insignificant memory leaks.

v9.39a for Windows (September 23rd, 2021):

  • Fixes a rare hang when working with cloud protocols.
  • Additional smaller fixes.

v9.39 for Windows, macOS, Linux (September 15th-21st, 2021):

  • Syncovery can now remember when a file was deleted. You can restore to a specific time and date in the past and get only the files which were not deleted at that time. Version 9.39 adds a checkmark “Remember deletion time and date” to the tab sheet Files->Deletions in each profile. This option should be used with “Move Deleted Files Into A Specific Folder…” but it can also remember the deletion date if deleted files are preserved in the “Older” folder specified on the Versioning tab sheet.
  • The checkmark “Restore deleted items” from the General Filters tab sheet will now retrieve deleted files from both “Older” folders as well as “folders for deleted files”.
  • The checkmark “Restore deleted items” has also been added to the Restore Wizard, but it will only be shown if the Restore is based on an existing profile that uses versioning or a folder for deleted files.
  • An inconsistent mix of 8-bit encodings (such as UTF-8 and Ansi) on (S)FTP servers and others can now be handled better, as well as an incorrect characters set choice on the Internet Protocol Settings dialog, tab sheet “Advanced”. However, support for deviating encodings is not 100% complete and only basic operations like listing, uploading, downloading, and deleting will work.
  • Additional smaller improvements, such as a corrected tab order of controls on the FTP dialog.

v9.38k for Windows (August 30th, 2021):

  • Binary Comparison now counts empty files as successful rather than skipped.
  • Fixes UI glitches
  • Minor logging improvements
  • No longer shows the combined final result of multiple passes as INCOMPLETE if a re-run was able to copy all files.
  • Fixes a Forbidden error uploading to WORM S3 buckets.
  • Fix a possible hang compressing json files.
  • Additional miscellaneous improvements and fixes.

v9.38j for Windows (August 26th, 2021):

  • Fixes a problem where only 500 changes were downloaded from Box every time the profile runs. This could cause new files and folders not to be detected unless the profile runs frequently enough.

v9.38i for Windows (August 24th, 2021):

  • updated TGPuttyLib based on PuTTY v0.76
  • updated Mega SDK
  • slightly less restrictive “never deletes all files” policy
  • allows up to one day of difference again when comparing old FTP timestamps that do not have a time of day, and when the file size is identical (can occur due to time zone and FTP listing format)
  • allows S3 to be used with credentials none / none for public buckets

v9.38h for Windows (August 19th, 2021):

  • The Graph protocol can now be used with sharepoint.de sites that have been migrated away from the old German Microsoft cloud.

v9.38g for Windows, macOS, and Linux (August 16th/17th, 2021):

  • Improved and more detailed recommendation dialog for filename encoding with S3 storages.
  • Adds a help button and a detailed choice dialog to help the user choose between Background Scheduler and Service Scheduler.
  • Can now correctly tell the difference between 00:00 and a missing time of day in FTP listings.
  • Adds a Secure Transfer checkmark on the first tab sheet of the FTP dialog, which is now checked by default. It basically duplicates the security setting from the Security tab sheet.
  • Adds support for DropBox refresh tokens.
  • Fixes an issue with subfolder selections.
  • Web GUI: fixes the folder selection button on the Internet dialog for Backblaze B2.
  • No longer warns for overdue jobs that are disabled.
  • Printing improvements for the Sync Preview (Windows only).
  • Mirroring folder timestamps is now on by default.
  • Adds Storj to the list of compatible S3 providers.
  • Fixes a bogus “Error” message when pausing and resuming a profile via the web GUI.
  • Additional minor improvements.

v9.38f for Windows (August 1st, 2021):

  • When using DropBox without the “Changes Based Listing”, you can now enable “Cache Destination File List” on the Special tab sheet instead of the usual changes based cloud cache.
  • Fixes an extremely rare hang during file list building.

v9.38e for Windows/Mac/Linux (July 24th/25th, 2021):

  • Fixes downloading from Box cloud, which was broken due to a change on the Box servers.
  • Fixes a situation where interrupted SFTP uploads with TGPuttyLib caused complete re-uploading rather than resuming.

v9.38d for Linux (July 18th, 2021):

  • The Linux version will now run as a limited free edition when the trial period is up.
  • Miscellaneous improvements.

v9.38d for Windows (July 11th, 2021):

  • The Windows version no longer complains about unrecognized fields when importing a profile from a csv file from the Linux version.
  • Additional cloud listing improvements relevant only in some very specific cases.

v9.38c for all platforms (July 9th, 2021):

  • Fixes a cloud listing problem, which affected only profiles that sync against the root folder of a cloud drive, when using the changes-based listing method. Some folders and files may have appeared as bogus duplicates in the root, in addition to their actual location further down the hierarchy. The update automatically cleans these incorrect items from the cloud cache database.

v9.38b for Linux (July 8th, 2021):

  • QNAP packages are now digitally signed.
  • Includes improvements from recent Windows updates.
  • Fixes a hang in 9.38/9.38a on negative timezones.

v9.38a for Mac (July 7th, 2021):

  • Retries deletions if files are locked.
  • Includes improvements from recent Windows updates.

v9.38a for Windows (July 6th, 2021):

  • Extends the new checkmark “Upload Only – Don’t Get Updated Listing From Cloud Server (Beta)” to Sharepoint, OneDrive, and Graph.
  • When the integrated User Management is used with groups, a user will now inherit individual profile rights from groups in addition to the general permissions.

v9.38 for Windows (July 5th, 2021):

  • Adds a way to avoid lengthy “Getting History” for Google Drive for upload-only profiles. Please see the new checkmark on the Advanced tab sheet of the Internet dialog: “Upload Only – Don’t Get Updated Listing From Cloud Server (Beta)”. This checkmark requires the Changes Based Listing checkmark to be chosen also.
  • Fixes a few cases where “Remember Results” of Binary Comparison did not work.
  • Adds an option to include unscheduled jobs in the Daily Summary emails.
  • Fixes a problem where a network connection configured on the Job tab sheet was not re-tried after an intial failure, even though the job is set to re-run after a number of seconds.
  • Adds ability to replace/update Azure BLOBs which are archived.
  • Adds checkmark to rehydrate archived Azure BLOBs where necessary (i.e. before download). The profile will finish with “rehydration pending” errors and needs to be re-run again after 24 hours to actually download the rehydrated files.

v9.37b for Windows (June 29th, 2021):

  • The new feature in 9.37 enabling Syncovery to remove empty folders via Internet Protocols even if they still contained metadata files and other useless files like Thumbs.db had a bug where other (potentially useful) files could be deleted too, if Syncovery thought the folder is empty. This has been fixed and only files known to be metadata or temporary files are now deleted.
  • Now uses the Glossy theme instead of Glow by default in Dark Mode in Windows 10.

v9.37a for Windows (June 27th, 2021):

  • Prevents files uploaded to Sharepoint from having two versions and using twice the size in cloud space. Sharepoint will still create two versions, but Syncovery then deletes the older one. Uploaded files will therefore have the initial version labeled “2.0”.
  • Adds the utility functions ConnDeleteFiles and ConnDeleteFilesOlderThan to PascalScript.

v9.37 for Windows (June 23rd, 2021):

  • Should fix a problem where Ransomware protection kicked in when real-time had to copy only a few files (Too many replacements error).
  • If chosen under “Security and Shares”->”Advanced” and/or “Alternate Data Streams”, Syncovery will upload .metadata-syncovery files to Amazon S3 for folders in cases where this previously wasn’t done (because empty folders aren’t supported for S3). Using the metadata files, empty folders can now be simulated.
  • Fixes Google Drive to Google Drive copying problems with native Google Documents (an Office filename extension was added even though the document type was kept as native Google Docs). To keep native docs native, use the same Google account on both sides. That way, the copying will be done within the Google servers and the files won’t be downloaded and reuploaded.
  • The PascalScript ConcatPath functions now also resolve and clean up double dots in paths, as in C:\Tests\SubOne\..\SubTwo.

v9.37 for Linux (June 21st, 2021):

  • The SSL Configuration page now offers to choose from certificates found in the Plesk default folder /usr/local/psa/var/certificates.
  • Automatically finds replacement certificates for expired certs in Plesk default folder, but also in the folder of a user chosen certificate if the certificate and private key are in the same file.
  • No longer applies file size filters to symlinks.
  • Can now delete .$symlink files.
  • Can now delete empty folders via Internet Protocol that still contain metadata files and other useless files like Thumbs.db.
  • .metadata-syncovery files will now be remembered by the file list cache so that extra destination folder scans can be avoided.
  • Now works correctly with backslashes in file names in the local file system.

v9.36e for Windows (June 19th, 2021):

  • Fixes Access Violations in some specific situations, caused by the new logging features in 9.36d (mostly when downloading checksum files generated by the remote service via Internet Protocol).

v9.36d for Windows (June 19th, 2021):

  • Adds a checkmark on the Program Settings dialog, tab sheet “Logs”,
    at the bottom: “Transfer Details” (especially for large files and resuming).
  • Many improvements in resuming broken transfers, and related logging, ensuring that incomplete copies are not deleted unless absolutely necessary.
  • You can add NeverLoseResumes=1 to the [Main] section of
    Syncovery.ini, which causes Syncovery to really never delete any partial file, and never restart a transfer from the beginning. However, this can cause some legitimate situations to result in errors, for example if an incomplete copy needs to be deleted because there’s a new file version to replace it (a resume is not possible because it’s a new file).
  • Now supports flushing file buffers when copying locally or in the LAN/VPN. You can activate this feature by adding FlushFileBuffersAfterMBs=100 or FlushFileBuffersAfterSeconds=5 to Syncovery.ini.
  • Fixes real-time sync not working in combination with “Use a single never-ending profile run”.

v9.36c for Windows (June 15th, 2021):

  • Includes subfolder selection fixes if the base folder is just a computername without a network share name (such as \\MYSERVER).
  • Fixes the ActionsCSVLogFile feature which has been broken in a few previous releases.
  • Minor improvements.

v9.36b for Windows (June 11th, 2021):

  • Putty and SecureBlackBox fingerprints are now stored in the same way so the same fingerprint is accepted after switching the SFTP Implementation.
  • Adds new PascalScript utility functions: GetProfileProperty, SetProfileProperty, CreateS3Connector, UploadFile, CloseConnector, AtomicAppendTextFileLine.

v9.36a for Windows (June 10th, 2021):

  • Adds more Wasabi storage datacenter regions.
  • Implements the “Allow IPV6” checkbox for TGPuttyLib (previously, IPV6 was always allowed).
  • Fixes a rare hang copying alternate data streams.
  • SSH fingerprint verification and prompts are now implemented for TGPuttyLib. To avoid problems, unknown SSH keys will be automatically accepted and remembered for ten days after installing the Syncovery update.
  • Small logging improvements with File Security Details.
  • Uses a lighter color for files being copied right to left in Dark Mode.

v9.36 for Windows (June 3rd, 2021):

  • Allows up to 12 files being uploaded in parallel to Sharepoint and OneDrive.
  • Adds a new checkbox to the Performance tab sheet of the Program Settings dialog: “Remove default threading limits and other program limits”.
  • On Backblaze B2, fixes renaming or moving multiple files simultaneously if each is over 5GB.
  • Fixes an MD5 mismatch error for Amazon S3 uploads with server side encryption.
  • Monitoring tool stability improvements and dark mode UI fixes.

v9.35f for Mac (May 30th, 2021):

  • Includes recent improvements from the Windows version.
  • Improved PCloud listing algorithm.

v9.35e for Windows (May 28th, 2021):

  • Fixes a problem where SmartTracking would re-created deleted folders, if trying to delete them on the other side has failed.
  • When resuming uploads via Internet Protocols, Syncovery will now drop back in the file a little to prevent possible corruption of blocks at the position around the end of the previously interrupted upload.
  • Fixes an error parsing PCloud listings when RAW photos are on PCloud.
  • Fixes two rare crashes.
  • Getting volume information is now done with a timeout to avoid rare hangs with network drivs.
  • If the destination path contains a variable, Syncovery will now update its modification timestamp when the job is run.
  • Resuming via FTP protocol no longer uses the APPEnd command.

v9.35d for Windows (May 26th, 2021):

  • Fixes a possible cause for Syncovery not seeing files and folders with unusual attributes (mostly on exFAT drives).
  • Now warns if a removeable drive is chosen via the Device button and the volume label is not unique. Syncovery needs the volume label to identify the drive.

  • Fixes downloading from a cloud protocol directly to an SSH or FTP server.

v9.35 for Windows (April 20th, 2021):

  • Adds a new Proxy setting for most cloud storages: “Use Windows Settings”. This will use the WinINet API rather than OpenSSL.
  • Fixes a bug when using compression when copying locked files, and the setting “Volume Shadowing: use for locked files”. The locked files would actually not be retried after the volume shadow was created.
  • Fixes possible errors when using the Sz format with higher encryption levels.

v9.34 for Windows (April 20th, 2021):

  • Adds the ability to turn Recycle Bin usage on or off in many profiles at once, using the Multi Edit Tool. Also to change the Move Files mode to overwrite identical or older files on the destination.
  • Detect renamed files now works in profiles that are not configured to detect deletions, i.e. in Standard Copying too.
  • Standard copying can now recurse into destination folders even if they don’t exist on the source side – see the new checkmark on the “Folders” tab sheet, which you will find only if you scroll it down – it’s checked by default on new profiles, but not checked on existing ones.
  • The Backblaze B2 b2_hide_file function now works with profiles that use the Destination File List Cache.
  • Fixes a problem where individual folders would not be read from Backblaze B2 correctly, when using the Destination File List Cache with the option to double-check individual folders.

  • Now applies Unicode C Normalization to all folder and filenames, like Syncovery for Windows.

v9.29e for Windows (January 28th, 2021):

  • Additional DropBox upload improvements, especially concerning the handling of internal server errors. It includes smart retrying and falling back to individual file commits rather than batch commits in case of server errors, avoiding the need to re-upload any files that could not be committed on the first attempt.

v9.29d for macOS and Windows (January 27th, 2021):

  • Fixes an Invalid Pointer Operation error at the end of profile runs that copy Zip Packages when run in attended or unattended mode.
  • Increases the number of Dropbox upload retries after a batch commit fails.

v9.29c for Windows (January 25th, 2021):

  • Fixes a bug in 9.29b where Syncovery would loop trying to delete split zip parts from Amazon S3 although these files don’t exist.

v9.29b for Windows and macOS (January 26th, 2021):

  • DropBox batch related fixes esp. with filename encryption, zip parts, split parts, and uploading new files to a folder that has been renamed in the same run.
  • Improved handling of split zip files in some cases.
  • Now tries to do a simple, direct API copying of a file if getting its status (reading its attributes) fails.

  • Includes improvements from recent Windows updates.

v9.29 for macOS (January 23rd, 2021):

  • Includes improvements from recent Windows updates.
  • Fixes the “Duplicate” item in the context menu on the Profile Overview.
  • Now defaults to using the mac API copyfile function rather than the internal copying algorithm, for better compatibility with some network storages.
  • No longer recommends to run as root if there are access denied problems – because these need to be fixed under Security & Privacy in the macOS System Preferences, and running a root will not help.

v9.29 for Windows (January 22nd, 2021):

  • Improved speed for the “Find Renamed Files” step.
  • Reinstates functionality of the “Different Delay for Older Versions” on the Exact Mirror Settings dialog box. This feature didn’t actually have any effect in recent Syncovery versions.

  • Fixes MIME types on Backblaze B2 uploads.

v9.28b for Windows (January 19th, 2021):

  • Numerous DropBox improvements, including batch folder creations and deletions. Folder renames and moves are now done with a single HTTP request. File renames and moves are still relatively slow, but done in a single thread only so they won’t delay uploads in additional threads.
  • The number of files copied in parallel can now be set up to 20 for DropBox and Rackspace.
  • Backblaze B2 renames and moves can now be done without re-uploading files.
  • The Sz format now stores (and restores) Windows file attributes (the simple file attribute DWORD).
  • Additional optimizations, bug fixes, and improvements.

v9.28a for Windows (January 12th, 2021):

  • Fixes a problem where Syncovery would sometimes reset various global program settings to 0 or 1, causing slow copying, unintended job splitting, and no logging. This happened mostly on new installations but some customers saw it on upgraded installations too. The affected Syncovery versions were v9.25a thru v9.28.

v9.28 for Windows (January 12th, 2021):

  • Implemented batch uploads to DropBox, greatly increasing upload speed when uploading many smaller files, and reducing HTTP errors and the necessity for retries.
  • Bug fixes.

v9.27b for Windows (January 7th, 2021):

  • Real-Time Sync now subscribes to NTFS permission changes too, and it works in both 1-way and 2-way syncs.

v9.27a for Windows (January 5th, 2021):

  • Fixes a status dialog window (“Cleaning up log files”) sometimes staying open even though everything is done.
  • Fixes a SmartTracking problem where deleted files were sometimes not detected when syncing with Sharepoint sites. The cause was that Sharepoint servers sometimes add metadata to uploaded Office documents, and these size changes could cause Syncovery to tag the online file as modified, which takes precedence over the deletion on the other side.

v9.27 for Windows (January 5th, 2021):

  • Now supports uploading to Amazon S3 buckets with automatic object locking.
  • Reinstates font colors in the Sync Preview, which had been just black or white since Dark Mode was added.
  • Updated cacert.pem certificates list.

v9.26e for macOS (December 31st, 2020):

  • Adds a new checkmark “Skip online-only files” to the General Filters tab sheet. This works with DropBox and possibly other cloud storage folders and will cause Syncovery to skip files in the local DropBox folder which are marked as online only.

v9.26e for Windows (December 30th, 2020):

  • Fixes a problem caused by recent optimizations that could cause Syncovery to not create a destination folder before trying to zip a file individually and directly to destination into that folder, causing a zipping error.

v9.26d for Windows (December 29th, 2020):

  • Fixes a problem where inefficient progress reporting could sometimes cause low copying speed.
  • Now tolerates cloud JSON listings with incorrect UTF-8 encodings (which is extremely rare).
  • Improves speed of checking for duplicate files, which is done when listing most cloud service folders.

v9.26b for Linux (December 26th, 2020):

  • Fixes a problem with incorrect scheduling, as well as profiles sometimes “losing” their schedule.
  • Additional improvements.

v9.26b for Windows (December 23rd, 2020):

  • It is now possible to make new connections with Google Cloud Storage again, after the previous Syncovery version had reached a user limit.
  • Fixes a compatibility issue of real-time polling of cloud folders and the setting “Minimum pause between actions”.

v9.26 for Windows (December 21st, 2020):

  • Adds complete support for Dark Mode. Colors and various new dark and light themes can be chosen by clicking on the Gears toolbar button and choosing “Themes and Colors…”

v9.25d for Windows (December 18th, 2020):

  • Fixes the “Run Attended” button on the Overdue Profiles dialog, which actually ran all profiles unattended rather than selected ones attended.
  • Fixes real-time uploads to DropBox sometimes ignoring the profile’s base folder and using the DropBox root as base folder instead.
  • Fixes unzipping of multi-part zip files, which could error out if there were additional, older (orphaned) zip parts from older versions of the file.
  • Optimized the handling of a “folder for deleted files” with cloud storage by not double-checking and re-reading the folder from the cloud server for each file that is to be moved into it.

v9.25a for Windows (December 16th, 2020):

  • Fixes a v9.25 bug that could prevent the scheduler from starting when installed as a service.

v9.25 for Windows (December 16th, 2020):

  • Some work in preparation for Dark Mode has been made; separate color sets for light and dark mode can be chosen.
  • MEGA SDK updated and made more stable.
  • Fixed a rare DB update error.
  • Now processes file listings from cloud services even if incorrect UTF-8 byte sequences are found.
  • Fixed filenames from WebDAV sometimes not being decoded (and containing %20 instead of spaces).
  • Fixed clean-up of unneeded synthetic backup files sometimes not working.
  • Contains a bug fix restoring split zip files.
  • Additional improvements.

v9.25 for macOS (December 15th, 2020):

  • Adds support for Dark Mode.
  • Adds support for the MEGA cloud storage service (Intel 64-Bit version only).
  • Additional improvements.

v9.23 for Windows and macOS (December 3rd, 2020):

  • The SmartTracking and cache databases can now hold paths up to 30,000 UTF-8 bytes long.
  • Fixes polling of cloud servers (for two-way real-time syncs), which did not seem to detect changes in subfolders and did not work on Mac.
  • Additional smaller fixes, including those from the Linux version 9.23.

v9.23 for Linux (December 2nd, 2020):

  • Adds a “Download Diagnostic File” button to the Program Settings dialog.
  • Adds a “Delete Database” button to the tab sheet Special->Database in the profile editing dialog. This can only delete SmartTracking and profile-specific cache databases, not cloud cache databases.
  • Log files now also mention the database size for SmartTracking and cache databases.
  • The SmartTracking and cache databases can now hold paths up to 30,000 UTF-8 bytes long.
  • Error results are now shown in red in the profile overview.
  • Fixes issues downloading symlinks from $symlink files which were also compressed.
  • Fixes various permission setting / restoring issues.
  • Improved profile locking which was not always respected by the scheduler.
  • Various additional improvements.

v9.22 for Windows (November 26th, 2020):

  • Implements retries for failed E-mail notification sending.
  • Automatically tries different SMTP ports and TLS settings if a notification can’t be sent.
  • Fixes a database error being shown a job’s final result summary caused by a path that is too long for the database. This error will still be logged, but not as the final result summary.
  • Additional smaller fixes.

v9.21 for Windows and Linux (November 22nd, 2020):

  • Adds support for Azure Shared Access Signatures (SAS URIs).
  • Adds the /CSVLOG=xxx command line parameter, which will log all copying, deleting and other actions to a CSV file. This can also be chosen by a Syncovery.ini line such as ActionsCSVLogFile=C:\Tests\Actions-$PROFILENAME.csv.

v9.20b for macOS (Apple M1/arm64) (November 21st, 2020):

  • First native release for Apple’s new CPU.

v9.20b for Windows (November 20th, 2020):

v9.20a for Windows (November 19th, 2020):

  • When the user clicks “Skip” while a cloud changes history is downloaded, the profile can now also be canceled.
  • Fixes problems with changes based cloud listings (esp. Google Drive) that could occur if a folder had been renamed and a file added to it during the same job run.

v9.20 for macOS (November 16th, 2020):

  • Includes all the improvements from the Windows version, especially synchronizing folder timestamps and permissions in two-way profiles.
  • Has been tested extensively on Big Sur (Intel).
  • Numerous macOS-specific bug fixes and improvements.

v9.20 for Windows (November 15th, 2020):

  • Now supports synchronizing folder timestamps in two-way profiles.
  • Also now supports synchronizing NTFS permissions in two-way profiles. To enable this, please see at the bottom of the Advanced tab sheet of the Security and Shares dialog.
  • The Security and Share dialog has been redesigned, with new two-way sync related settings on the Advanced tab sheet.
  • A new checkmark for permissions: “Compare permissions of existing items only if recently accessed”. This should speed up the scanning/comparison phase without missing any changes in NTFS security setting.
  • The Syncovery Remote Service has been updated to also support this new checkmark and include only the NTFS security info for recent items in the listing.
  • The new feature “Copy Pinned Files Only” can now be chosen separately for the left and right sides.
  • Better handling of HTTP error 416 when uploading to Box (which can sometimes occur if a chunk is re-uploaded after a timeout or server error).
  • Improved TGPuttyLib and compatibility with the Sz format in conjunction with “Verify copied files”.
  • When copying from an Internet Protocol to another Internet Protocol and using the Sz format for compression and/or encryption, previous versions would actually do the Sz processing twice (once during download and then again during upload), resulting in a redundantly double-Sz’ed file. This has been fixed.
  • The new version can now correctly unpack/restore such redundant double-Sz’ed files.

v9.19 for Windows (November 4th, 2020):

  • Adds two new settings to the “General Filters” tab sheet, which are mostly relevant when copying the local OneDrive folder: “Skip Offline Files” and “Copy Pinned Files Only”. Pinned files are those with the checkmark “Always keep on this device” in Windows Explorer.
  • Adds the FileCopy function to the PascalScript language.

v9.18f for Windows (November 3rd, 2020):

  • Improves Sharepoint/Graph library selection dialog, which is more complete now, and works with some Sharepoint accounts that don’t list the sites as sub-sites of the root site.

v9.18e for Windows (October 27th, 2020):

  • Fixes subfolder selections being reset by the selection dialog for older profiles with UNC base paths.

v9.18d for all platforms (October 24th/25th, 2020):

  • Can enumerate network shared with a lesser user account level (Windows only)
  • Adds RemoveEmptyFoldersOnlyOneLevelWhereAFileHasBeenRemoved PascalScript variable
  • Fixes cloud related errors such as “Uploading to a folder that has not been read” and “Duplicate Folder Detected” (esp. with Box)
  • various additional improvements and bug fixes

v9.18b for Windows (October 21st, 2020):

  • Fixes Synthetic Backup not working in v9.18a in some cases.

v9.18a for Windows (October 18th, 2020):

  • Moved “Replace Paths in Profiles” back to the File menu.
  • Fixed a zipping error “Multi-spanned archive is not allowed for modification”.

v9.18 for Windows (October 16th, 2020):

  • Fixes a cloud upload error “Uploading to a folder that has not been read”.

v9.17a for Windows (October 15th, 2020):

  • Allows up to 1000 listing threads on the Program Settings dialog, tab sheet Performance.
  • Ensures that the incompatible option “Cache Destination File List” is not used with Sharepoint/Graph/OneDrive.
  • Fixes a cloud folder listing issue.

v9.17 for Windows, Mac, Linux and FreeBSD (October 12th/13th/14th, 2020):

  • Can now generate new private/public key pairs for use with SSH/SFTP (in the desktop GUIs only).
  • Fixes a bogus “duplicate folder” error with Microsoft Azure which could occur when folders had been created with other software, or the Azure management console.
  • Fixes uploading errors to Google Cloud Storage.
  • Cloud stability improvements.
  • First FreeBSD release of Syncovery 9.

v9.16 for Windows (October 5th, 2020):

  • Compressed Archives/Package filenames are no longer encrypted. Only the contained files will be encrypted. The zip/sz archive itself will have a regular name with file extension, such as Backup 12884.12888.33554434.12888-2020-10-02 22.45.44.zip. This change also fixes an error 217 when the archive is copied to the destination.
  • Fixes hangs with the Mega API.
  • Adds a caching mechanism for IP addresses (resolved domain names) to reduce DNS queries and/or operating system function calls.
  • Stability and hang reporting improvements with multithreaded operations.
  • Google Cloud Storage authorizations are now requested with a higher level again to allow metadata manipulation of existing files, such as timestamp setting.
  • Various additional improvements and bug fixes.

v9.15 for Mac and Windows (September 28th, 2020):

  • First Mac Release of Syncovery 9.
  • Cloud Cache Databases for Google Drive, DropBox, Box, and OneDrive/Sharepoint/Graph now store an additional flag to confirm that empty folders have been scanned and confirmed to be empty. This allows Syncovery to work correctly even if the subfolder selection for an existing profile is modified by the user, and some folders aren’t present in the cache yet. Syncovery 9.15 will have to re-confirm all empty folders once when you run a cloud based profile the first time after updating. This can result in a longer folder scanning process (only once per profile).
  • Should fix an issue where Syncovery would not see some folders on OneDrive.
  • Makes email and MTP destinations compatible with zip and sz packages (to send multiple files per email).
  • Now automatically disables some extended logging settings every 24 hours to avoid unnecessarily big log files.
  • Various additional minor improvements and bug fixes.

v9.08 for Windows (August 5th, 2020):

  • For Google Drive and Sharepoint/OneDrive/Graph, adds a checkmark on the second tab sheet of the Internet dialog that allows to use the changes-based listing “Except For First Scan (scan folders directly if cache database is empty)”. This choice is on by default for new profiles, to avoid lengthy history processing.
  • Fixes a possible lockup when the max. number of profiles per process is set to 1.
  • Fixes unnecessary logging to Syncovery_realtime_status_log.txt, which could cause it to become quite large.

v9.07e for Windows (August 4th, 2020):

  • Fixes an Access Violation that could occur if two profiles simultaneously try to access the same cloud cache Sz archive file. This could cause the cloud cache database to be deleted, which could cause a lengthy re-scan or re-processing of the folders or changes history.

  • Fixes email notifications sometimes not being sent, or not containing the log file as attachment.
  • Additional bug fixes.

v9.05 for Windows (July 3rd, 2020):

  • Uses a new, advanced ETA algorithm that takes different copying speeds of smaller and larger files into account, as well as different speeds for uploading and downloading, and also measures the speeds of additional actions such as deletions and renames, and takes them into account.
  • A new checkmark “Empty Folders” on the Sync Preview allows you to hide and show empty folders, and also prevent the creation of empty folders (if you forgot to remove the Empty Folders checkmark in the profile and you don’t want them).
  • No longer attempts to upload files over 100 MB to Google Drive for conversion into native Google Docs. Instead, the original file format will be preserved on upload. Also falls back to unconverted uploads if the converted upload fails (rather than retrying many times).
  • Uses a newer version of Windows’ Browse for Folder Dialog.
  • Adds UseBinaryCompToAvoidCopying variable for PascalScripts.
  • More quickly skips over folders that can’t be deleted.
  • Fixes a problem that could occur if the folder for deleted files was on the top level of a cloud strage (such as /Deleted).

  • Additional fixes.

v9.04a for Windows (June 25th, 2020):

v9.04 for Windows (June 24th, 2020):

  • Contains updated libraries for Internet Connectivity, especially for FTP. All protocols can now verify SSL/TLS server certificates correctly, including hostname verification.
  • Fixes notification emails sometimes being sent although not selected for that case, and includes a more precise reason why the email was sent or not in the log file.

v9.03c for Windows (June 20th, 2020):

v9.03b for Windows (June 20th, 2020):

  • Fixes bugs in the changes based listing method for some cloud services, which could cause various error messages in log files as well as delays.

v9.03a for Windows (June 19th, 2020):

  • Optimizes progress reporting during folder scanning phase.
  • Fixes the INI file entry SkipProfileListAuthForIP=

  • Fixes the program password prompt dialog when opening the Syncovery main program.

v9.02b for Windows (June 9th, 2020):

  • Fixes the local timezone not being used during the first 10 minutes after rebooting. Syncovery now checks for timezone changes every 10 minutes, but before this update, it didn’t check unless the last boot was longer than 10 minutes ago.
  • Prevents ever using AWS Signature V4 for servers like Wasabi, which are S3 compatible. Wasabi actually does support Signature V4 but apparently not in the exact same way as the original S3, so Syncovery’s V4 signatures failed with Wasabi.

v9.02a for Windows (June 9th, 2020):

  • Fixes lockups.

v9.02 for Windows (June 8th, 2020):

  • Fixes the obsolete SCP and the experimental “Pure SSH” protocols.
  • Allows up to 10 parallel uploads or downloads to and from DropBox (use carefully – can cause penalty delays).
  • Adds the first instalment of a REST API – when the browser based web interface is active, you can use profilelist.json to get a machine readable profile list with status and scheduled times etc. This read-only profilelist.json can be accessed without authentication if you use the INI file lines SkipProfileListAuth=1 or SkipProfileListAuthForIP=
  • Fixes some registry entries being made although the program is used in portable mode.

  • Additional smaller improvements.

v9.01 for Windows (May 27th, 2020):

  • Improved getting and setting of file attributes and timestamps, which should result in a slight speed advantage and improved reliability of timestamp setting after files have been copied, especially with non-Windows drives (such as network drives or driver letters provided by third party apps).
  • The Graph protocol can now access multiple users’ OneDrives, provided that the user is a Site Administrator for these OneDrives, or that Syncovery is given domain specific App Registration details and Admin Consent is granted via portal.azure.com (email us for detailed instructions).
  • Adds new PascalScript hooks OnCanRunProfile and OnGetNextRunTime, as well as a few helper functions.
  • Log-on, Log-off, and shutdown/reboot jobs can now be run via the service.

  • Will now properly perform a new Mega login if the previous session was terminated by the user in the Mega security sessions.
  • Fixes compressing or encrypting to Sz files if the source side uses an Internet protocol.

v9.00b for Windows (May 7th, 2020):

  • Removes a bogus Progress window that appeared with real-time profiles that used the mode “Process Each File Event Individually”.
