  • Mac only: fixes inability to zip some special filenames.
  • Mac only: fixes handling of colons in the base paths.


  • Fixes a rare problem when using the volume shadowing setting “Use For All, Create Shadow Before Building File List”. On older Windows machines (especially Windows XP), it could occur that the volume shadow “goes away” while the file list is being built. In some cases, this could cause folders to be detected as deleted folders even though they still existed. This issue has been fixed.
  • Mac only: can now download files from Google Drive that contain umlauts and were uploaded on Mac but not with Syncovery.


  • In the Profile Overview, you can now enable/disable all selected profiles at once.

  • Implements a new functionality for real-time synchronization in conjunction with a time window.
    The program can now monitor the folders for changes all day long but do the copying only within the specified time window. To take advantage of this functionality the following settings need to be combined:

    • Schedule: no schedule on the Schedule tab sheet
    • Real Time Sync selected on the Monitoring/Realtime tab sheet
    • Real Time Settings:
      • the checkbox “Run profile entirely once” must be deselected
      • “Process Complete Folders” must be chosen (on Windows only)
    • Weekdays and Time Window:
      Specify the time window when it should do the copying.


  • Fixes a WebDAV incompatibility.

  • Macintosh: Now compatible with Mac OS X 10.8 “Mountain Lion”
  • Windows: Fixes printing of the Sync Preview which was broken.

v6.00a, build 101 (Mac only):

  • fixes some registration codes not being recognized.

v6.00, build 100:

  • Initial Syncovery Release.
