PascalScript in Syncovery

Syncovery includes a PascalScript engine, allowing you to customize your profile’s behavior in many ways. PascalScript was added in Syncovery 8, and many new hooks and functions have been added since the first release.

To change a particular behavior, you need to write a hook function and write some code. In most cases, our tech support will write the code for you. For larger or complicated scripts, please consider a Premium Support Subscription that includes custom script development.

The script is specified in the profile via the “Pascal Script…” checkmark on the Job settings category tab sheet.

PascalScripts have access to all profile settings and can read and modify them using the utility functions GetProfileProperty and SetProfileProperty.

Useful ready-to-use scripts

The following scripts can be used as it is, just paste the script into the PascalScript dialog.

  • Shorten long paths
    This script shortens file names if the total path becomes over 250 characters long. It adds a CRC32 hash based on the original file name to ensure that the shortened names are unique. Folder names are not modified. The shortened names are used only when copying from the left side to the right side. The left side remains untouched.
  • Shorten long file names
    This script shortens file names which are over 114 characters long, adding a CRC32 hash based on the original file name to ensure that the shortened names are unique. Like the previous script, folder names are not modified, and the shortened names only affect the right side.
  • Convert Disallowed Characters for Windows
    This script allows you do have the disallowed characters /:\?|<>“* in file names on the left-hand side. The right-hand side can be Windows compliant storage such as a local NTFS drive.
  • Simple E-Mail Notifications
    This script simplifies the e-mail notifications and can be edited easily to customize your emails.
  • Send E-Mail Notifications Depending on Profile Results
    This script causes e-mail notifications to be sent only if less than 10 or more than 100 files were copied from left to right.
  • Bind an FTP connection to a specific LAN port
    This script allows you to specify which LAN port to use for an FTP connection. Note that this works with FTP library 3 only (on Windows) or 2 (on other platforms).
  • Delete files older than 30 days from the source (left) side
    This script will make Syncovery delete older files from the source side of a one-way synchronization. The source side must be the left-hand side. The right-hand side will serve as an archive where all historical files are kept, whereas the left side only contains the files from the last 30 days. New files are assumed to appear on the left-hand side only. The profile should be used with the “Standard Copying” operation mode only. The number of days can be adjusted in the script. You can also choose whether to delete newly copied files (unlikely because they’re probably not older than 30 days), and/or files which already exist on both sides when the job runs (the more likely case).

OnActionComplete Sample Script

This hook is called after any type of file or folder related action has been carried out, such as a file copied, moved, or deleted and so forth. The example just logs the action. The function result is ignored by Syncovery.

function OnActionComplete(const StartTimeUTC, CompletionTimeUTC: Double;
        const Success: Boolean;
        const ActionStr, DirectionStr, Filename,
              LeftFile, RightFile, Subfolder, MovedTo,
              ErrorMsg: UnicodeString;
        const ResultCode: Int64;
        const ErrorSide: UnicodeString;
        const ASize,ACompressedSize:Int64):Boolean;
  Log('Action Complete: '+ActionStr+' '+DirectionStr+' '+Filename);

OnAfterFileCopy Sample Script

This hook is called after a file has been copied. The function result is ignored by Syncovery. It is used by the sample script “Delete files older than 30 days from the source (left) side”.

function OnAfterFileCopy(const DirectionIsL2R:Boolean;
        const Source,Dest,DestPath,LeftSubPath,RightSubPath:UnicodeString;
        const ResultCode:Int64):Boolean;
  Log('File Copy Complete: '+Source+' to '+Dest);

OnCanRunProfile Sample Script

This hook is called when the scheduler is about to run a profile. You can decide if it should actually run now, or be postponed. The example uses the hook to prevent two particular profiles from running at the same time, or overlapping. This script must be entered as a Global PascalScript via the Program Settings dialog, tab sheet Advanced.

const p1='Profile Name 1';
      p2='Profile Name 2';

function OnCanRunProfile(const ProfileName:UnicodeString; var PostponeBySeconds:Integer):Boolean;
  if ProfileName=p1 then
     Result:=not ProfileRunning(p2)
     if ProfileName=p2 then
       Result:=not ProfileRunning(p1)
  if not Result then

OnFileCopy Sample Script

This hook allows you to replace the file copying logic. Return 0 on success, -1 if Syncovery should do the copying a usual, or any other value as an error code.

function OnFileCopy(const DirectionIsL2R:Boolean;
        const Source,Dest,DestPath,LeftSubPath,RightSubPath:UnicodeString;
        const SourceConnector,DestConnector: Opaque):Int64;
  Result:=Execute('XCOPY.EXE "'+Source+'" "'+DestPath+'"',60);

OnGetCustomHeaders Sample Script

This hook allows you to add custom HTTP headers to Amazon S3 requests. In future Syncovery versions, this feature can be added to other cloud storages and protocols (on customer request – just ask for it).

function OnGetCustomHeaders(const RelativePath: UnicodeString;
        const URL:AnsiString;var MIMEType, Headers: AnsiString;
        const Connector:Opaque):Boolean;
var strDate:string;
  Headers:='Cache-Control: 10';
  Log('Headers Added to '+RelativePath);

OnGetNextRunTime Sample Script

This hook allows you to modify the scheduling. The best way to use it is to give the profile a regular, simple schedule, and use the hook to skip undesired run times. This example is intended for a profile that is scheduled to run “every day at XX:YY”. The hook ensures that in fact it runs only on the first weekday in a month.

function OnGetNextRunTime(const LastRun, ProposedNextRun: Double):Double;
var DidItRunThisMonth:Boolean;
  DidItRunThisMonth:=(MonthOf(LastRun)=MonthOf(Now)) and
      (MonthOf(LastRun)=MonthOf(ProposedNextRun)) and
  if DidItRunThisMonth then begin
    // go to the next month
    while DayOf(Result)>1 do
  else begin
    // go to the next month if we are beyond week #1
    while DayOf(Result)>7 do
  // second, advance further until it's not a weekend
  while DayOfTheWeek(Result)>=6 do

OnIncludeItem Sample Scripts

The OnIncludeItem hook is called individually for each side of the synchronization. The isRightSide parameter indicates which side we are currently looking at.

The following script serves to exclude files without filename extension. Such an exclusion is not possible via the Exclusion Masks.

function OnIncludeItem(const FileName, RelativePath: UnicodeString;
        const isRightSide, isFolder:Boolean;
        const FileSize:Int64; const FileAttr:LongWord;
        const Connector: Opaque):Boolean;
  Result:=isFolder or (Pos('.',FileName)>0);

The second example for OnIncludeItem will only process subfolders that contain the file READY.toprocess, as well as any subfolders that exist on the right-hand side.

function OnIncludeItem(const FileName, RelativePath: UnicodeString;
        const isRightSide, isFolder:Boolean;
        const FileSize:Int64; const FileAttr:LongWord;
        const Connector: Opaque):Boolean;
  Result:=isRightSide or not isFolder or

OnScanFolder Sample Script

This is probably a better way to look for ‘READY.toprocess’. The OnScanFolder hook is called just before the folder would be scanned, and knowledge of both sides can be used in the hook.

function OnScanFolder(const FolderLevel: Integer;
        const RelativePath, LeftCompletePath, RightCompletePath: UnicodeString;
        const LeftExists,RightExists:Boolean;
        const LeftConnector, RightConnector: Opaque):Boolean;
  Result:=RightExists or ConnFileExists(LeftConnector,LeftCompletePath+'\READY.toprocess');

OnProfileResults Sample Script

This script does nothing, but the function is called with some statistics when a profile completes. An example with some real use can be downloaded near the top of this page (“Send E-Mail Notifications Depending on Profile Results”). This functions return value (“Result”) is ignored.

function OnProfileResults(const FilesCopiedL2R,FilesCopiedR2L:Integer;
        const FilesToCopyL2R,FilesToCopyR2L:Integer;
        const BytesCopiedL2R,BytesCopiedR2L:Int64;
        const ResultString:UnicodeString;
        const Error:Boolean):Boolean;

OnNormalizeFilename Sample Script

This hook allows you to “normalize” filenames so that Syncovery can see file names as identical despite minor differences. The sample script normalizes space characters, so that there will always be only one space character between other characters. Two or more consecutive spaces are normalized to just one space. The result is that Syncovery sees files as identical which have different numbers of consecutive spaces on each side of the profile. These filenames are not modified on disk. The modification is purely in memory for comparison purposes. The Sync Preview will show the normalized file names.

function OnNormalizeFilename(const FileName: UnicodeString;
        const isFolder, isRightSide: Boolean):UnicodeString;
var Changed:UnicodeString;
    Changed:=StringReplace(Result,' ',' ',true);
    if Changed=Result then
    until false;

OnReplaceFilenameLeftToRight Sample Script

This script will rename files when the file is copied from left to right. In our example, ‘-draft’ is added before the filename extension.

function OnReplaceFilenameLeftToRight(const FileName: UnicodeString;
        const isFolder: Boolean):UnicodeString;
  if isFolder then

OnReplaceFilenameRightToLeft Sample Script

If you do a two-way sync, and new files might appear on the right-hand side, we also need a way to rename in the other direction. This sample script removes the ‘-draft’ insert from the names.

function OnReplaceFilenameRightToLeft(const FileName: UnicodeString;
        const isFolder: Boolean):UnicodeString;
var ToFind:UnicodeString;
  if isFolder then
  else begin
    if p>0 then

OnUploadComplete Sample Script

This script will set permissions for files uploaded via FTP to 777.

function OnUploadComplete(const FileName, LocalFilePath, CompleteURL: UnicodeString;
        const isRightSide:Boolean;
        const FileSize:Int64;
        const Connector: Opaque):Boolean;
var CmdRes:Int64;
  CmdRes:=ConnCustomFTPCommand(Connector,'SITE CHMOD 777 '+FileName,200,200,200,ResponseText);
  Log('Set Permissions for '+FileName+': '+ResponseText);

OnDownloadComplete Sample Script

This script will rename downloaded files by adding an additional “.downloaded” extension.

function OnDownloadComplete(const FileName, CompleteURL, LocalFilePath: UnicodeString;
        const isRightSide:Boolean;
        const FileSize:Int64;
        const Connector: Opaque):Boolean;
  if ConnRenameFile(Connector,CompleteURL,FileName+'.downloaded') then
    Log('Renamed '+FileName+' to '+FileName+'.downloaded')
    Log('Rename failed: '+FileName+' to '+FileName+'.downloaded');

OnVolumeShadowComplete Sample Script

This script will execute an external command (batch or CMD file) just after a volume shadow has been created.

function OnVolumeShadowComplete(const Volume,ShadowPath:UnicodeString):Boolean;

OnBeforeFolderCreate Sample Script

This script will prevent any folder creation except where necessary to copy files to the destination. You can also use this hook to manipulate folder paths on the destination.

function OnBeforeFolderCreate(const DirectionIsL2R:Boolean;
        var Source,Dest,Reason:UnicodeString):Boolean;

OnBeforeFileCopy Sample Script

This script will manipulate the destination paths for copying (left to right), by adding an additional subfolder ‘archive’ which is not present on the source side.

function OnBeforeFileCopy(const DirectionIsL2R:Boolean;
        var Source,Dest,DestPath,LeftSubPath,RightSubPath:UnicodeString):Boolean;
var AddFolderName,NewDestPath,NewDest,NewRightSubPath:UnicodeString;
  if not DirectionIsL2R then
  if not MakeSurePathExists(NewDestPath,true) then begin
    Log('Could not create '+NewDestPath);
  Log('DestPath:'+DestPath+' changed to '+NewDestPath);
  Log('Dest:'+Dest+' changed to '+NewDest);
  Log('RightSubPath:'+RightSubPath+' changed to '+NewRightSubPath);

OnBeforeFileUpload Sample Script

This script is called before a file upload via Internet Protocol and can be used to modify the upload behavior. The sample function below will invoke an anti-virus scanner before the upload.

function OnBeforeFileUpload(const DirectionIsL2R:Boolean;
        var Source,Dest,DestPath,LeftSubPath,RightSubPath,ErrorMsg:UnicodeString;
        var ErrorCode:Int64):Boolean;
  if not DirectionisL2R then begin
  Result:=Execute('"C:\Program Files\ClamAV\clamscan.exe" '+Source,60)=0;
  if Result then
    Log('Virus scan OK: '+Source)
  else begin
    Log('Virus scan failed, not uploading: '+Source);
    ErrorMsg:='Virus detected';

OnHttpPost Sample Script

This hook can be used to enable file upload via HTTP protocol. The script needs to set relevant headers and form properties.

function OnHttpPost(const RelativePath : UnicodeString;
        var URL, MIMEType, Header : AnsiString; var LAsForm : Boolean;
        var LFormData : AnsiString;
        const Connector : Opaque) : Boolean;
  URL := '';
  Header := 'Authorization: Bearer abcdefghijklmnopqrstuvwxyz';
  LAsForm := true;
  Result := true;
  LFormData := 'orderstates';
  Log('Header Added to '+RelativePath);

OnGetProfilePathBeforeListing Sample Script

This script uses this hook to specify an individual TEMP folder for the profile. The original purpose of the function is to modify the left or right path and/or the credentials.

function OnGetProfilePathBeforeListing(const isRightSide:Boolean;
        var Path,UserName,Password:UnicodeString;
        var AuthKey,AuthKeyPassword:AnsiString;
        var Port:Integer):Boolean;

OnGetProfilePathBeforeCopying Sample Script

This hook can be used to modify the path and/or credentials. The sample script doesn’t do anything.

function OnGetProfilePathBeforeCopying(const isRightSide:Boolean;
        var Path,UserName,Password:UnicodeString;
        var AuthKey,AuthKeyPassword:AnsiString;
        var Port:Integer):Boolean;

OnBeforeMainActionPhase Sample Script

This script lets the job run only if a fixed number of files is to be copied from left to right.

function OnBeforeMainActionPhase(const CopyL2RCount,CopyR2LCount,DeleteLCount,DeleteRCount,MoveLCount,MoveRCount:Int64;
                const CopyL2RBytes,CopyR2LBytes,DeleteLBytes,DeleteRBytes,MoveLBytes,MoveRBytes:Int64):Boolean;
  if CopyL2RCount=14 then
  else begin
     Log('Not continuing because CopyL2RCount is '+IntToStr(CopyL2RCount));

OnCloudConnect Sample Script

This script can be used to log into a web site when using the HTTP protocol to download files from a URL.

function OnCloudConnect(const URL:AnsiString;
                const isRightSide,isFirstConnectionInJob:Boolean;
                const Connector: Opaque):Boolean;
  if isFirstConnectionInJob and not isRightSide then

OnCloudDisconnect Sample Script

This hook is called before the final disconnection from a cloud or FTP server at the end of a profile run.
It can be used to perform some final tasks.
The sample script doesn’t do anything.

function OnCloudDisconnect(const URL:AnsiString;
                const isRightSide,isMainConnectionInJob,isFinalDisconnection:Boolean;
                const Connector: Opaque):Boolean;
  Log('Before final disconnection');

OnLogFileClosed Sample Script

This script copies the log file to another folder after the log file has been closed.

function OnLogFileClosed(const FileName:UnicodeString):Boolean;

OnMoveFileToDeletedFolder Sample Script

This script prevents keeping multiple versions of deleted files by first deleting the potentially existing file from the folder for deleted files.

function OnMoveFileToDeletedFolder(const Path:UnicodeString;
                var MoveToPath:UnicodeString;
                var proceedToDeleteInsteadOfMoving:Boolean;
                const Connector:Opaque):Boolean;
  if FileExists(MoveToPath) then FileDelete(MoveToPath);

OnNeedToRerun Sample Script

This script causes the job to be rerun until the expected condition has been met (at least one file has been copied).

function OnNeedToReRun(const FilesCopiedL2R,FilesCopiedR2L:Integer;
                const FilesToCopyL2R,FilesToCopyR2L:Integer;
                const BytesCopiedL2R,BytesCopiedR2L:Int64;
                const ResultString:UnicodeString;
                const Error:Boolean):Boolean;
  if FilesCopiedL2R+FilesCopiedR2L>0 then
