Cross-platform file sync utility
FreeFileSync is a folder comparison and synchronization software that creates and manages backup copies of all your important files.
Instead of copying every file every time, FreeFileSync determines the differences between a source and a target folder and transfers only the minimum amount of data needed.
FreeFileSync is Open Source software, available for Windows, macOS, and Linux.
