Software Product Description

FreeFileSync is an Open-Source folder comparison and synchronization tool. It is used for fast and easy configurable sync operations between two folders without restricted or overloaded UI interfaces.


  • Compare files (bytewise or by date) and synchronize them.
  • No limitations: An arbitrary number of files can be synchronized.
  • Subfolders are also synchronized, including empty folders.
  • Network support.
  • Lean & easy accessible UI: Highly optimized for speed and huge sets of data.
  • Algorithms coded in C++ completely.
  • Focus on usability:
    • Only necessary functionality on UI: no overloaded menus or icon jungle.
    • Select folders via drag & drop.
    • Last configuration and screen settings are saved automatically.
    • Maintain and load different configurations by drag&drop, load-button or commandline.
    • Double-click to show file in explorer.
    • Copy & paste support to export file-lists.
    • Delete superfluous/temporary files directly on main grid.
    • Right-click context menu.
    • Progress indicators, status information and error reporting.
    • Sort file-lists by name, size or date.
    • Display statistical data: total filesizes, amount of bytes that will be transfered with the current settings.
  • Easy configurable commandline mode for automated synchronization.
  • Support for filesizes > 4 GB.
  • Option to move files to Recycle Bin instead of deleting/overwriting them.
  • UTC (coordinated world time) is used when comparing file times avoiding problems with time zones or daylight saving time.
  • Automatically ignore directories "\RECYCLER" and "System Volume Information" when comparing and syncing.
  • Localized German version available.
  • Delete before copy: Avoid disc space shortages with large sync-operations.
  • Based on wxWidgets framework => Portable to many operating systems.
  • Filter functionality to include/exclude files from synchronization (without re-compare!).
  • Include/exclude specific files from synchronization manually.
  • Create sync jobs via GUI to synchronize automatically (can be scheduled or executed directly).


"Great sync program!"

Pros: I've used FFS for years, and I finally made a donation, that's how good I think it is! The freeware version is still a great program, and I personally have never had any issues with unwanted software being installed on my PC, unlike others have suggested. If you don't want to use FFS, the next best freeware sync program is SyncBack free, which is also very good. I've tried most ALL the sync programs over many years, and FFS and SyncBack are hard to beat IMHO.

Cons: None that I can see.

Other Thoughts: If you look at the reviews, I first reviewed FFS back in 2008, and I'm STILL using it today!
