FreeFileSync

FreeFileSync is powerful open-source software designed to synchronize files and folders across Windows, macOS, and Linux. It smartly compares source and destination folders, identifying only the differences between them. This ensures that instead of performing full copies every time, it transfers solely the data that has changed, saving both time and storage space. It is an essential tool for creating and managing reliable backups of your important documents, photos, and other files with precision and speed.
