FreeFileSync

FreeFileSync compares files and folders in different locations, then synchronizes them so their contents stay aligned. It also lets you set up and run data backups, helping organize routine work with files stored in separate places. Visual feedback shows what the software is doing during comparison, synchronization, and backup operations.

A typical workflow involves selecting the folders involved, reviewing the comparison, and starting the synchronization or backup task. This suits people who need to keep data consistent across locations or manage recurring backup work on a Mac. The program is useful for personal file organization and other system-tool tasks where seeing the operation’s progress matters.

Developed by Zenju, FreeFileSync is released under an open-source license. It supports Windows, macOS, and Linux, with this entry intended for macOS. Its distinguishing feature is the combination of folder comparison, synchronization, backup setup, and visible process information in one utility rather than concentrating on only one of those functions.
