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.

Features:

• 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).

• Copy file and folder create/access/modification times when synchronizing
