FreeFileSync is an Open-Source folder comparison and synchronization tool. It is optimized for the highest performance and usability without restricted or overloaded UI interfaces.
FreeFileSync enables you to synchronize files between two folders or drives. You can 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 supports Unicode and Networks. Its synchronization database propagates deleted files and detects conflicts. It also supports multiple folder pairs with distinct configurations.
Full support for Windows Symbolic Links and Junction Points is available. Additionally, the program offers an Update mode that copies only new or modified files.
