FreeFileSync

FreeFileSync is a powerful Open Source tool for synchronizing files and folders across Windows, macOS, and Linux. It intelligently compares source and destination folders, identifying only the differences between them. This means it transfers solely the data that has changed, saving you significant time and bandwidth compared to full copy operations. It's ideal for creating and managing backups, mirroring folders, or simply keeping files consistent across multiple devices. The software ensures your important data is always up-to-date with minimal effort.
