  • Improved: Upload resume optimizations


  • New: One-way file move (transfer & delete)

    All files in the source folder are transferred to the target, and after 100% successful transfer, they are deleted on the source. In other words, files are moved from the source to the target. If a certain file is not transferred in full, it is not deleted on the source. You can create a hot-folder sync task that is configured like this:

    c:\OutBox -> ftp.yourserver.com/InBox

    And all files copied to the c:\InBox (and its subfolders), are moved to the remote /InBox. The sync task can also be set up in reverse:

    ftp.yourserver.com/OutBox -> c:\InBox

  • Fixed: Bug: If target parent dir creation fails, flag all sub-items with error message when sync completes, show correct stats


  • With new MLST/MLSD command support, FTP server lists file time with seconds. Before this, unix servers never included seconds in file timestamp, and they also dropped time altogether for files older than 6 months. This new feature requires that server supports MLST/MLSD commands.


    The MLST/MLSD cmd support might trigger transfer of some extra files on unix FTP servers that support this new MLSD command. This is because servers start to report file time with seconds, and therefore some remote files look like they have changed. To avoid transfer of these files, do like this:

    1) Run sync with your current version
    2) Download and install new 2.0.40 release
    3) Edit Task > Comparison-tab > check Only reset SyncDB file on next run
    4) Run sync with this new release, this will update remote file time info (now including seconds) without transferring any files
    5) Done
