FreeFileSync is an Open-Source folder comparison and synchronization tool. It is optimized for highest performance and usability without restricted or overloaded UI interfaces.

FreeFileSync enables you to synchronize files between two folders or drives. You can either mirror two folders to create an exact copy of the source folder. Or perform a two-way synchronization that will copy new or updated files in both directions.

FreeFileSync has Unicode support and Network support. Synchronization database for propagation of deleted files and conflict detection. Also supports the multiple folder pairs with distinct configuration.

Full support for Windows Symbolic Links and Windows Junction Points also is available. Furthermore, the program supports an Update mode which will only copy files that are new or have been changed.
