Visit FreeFileSync

FreeFileSync is open-source folder comparison and synchronization software for Windows, macOS, and Linux. It compares a source folder with a target folder and transfers only the differences needed to bring them into sync, rather than copying every file on each run. It can also create and manage backup copies of files.

The software supports Two way, Mirror, and Update synchronization modes, with directions set from differences or from changes recorded in a database file. It includes multi-file renaming, parallel file copying, and support for Google Drive, SFTP, and FTP(S). Email notifications of synchronization logs are available in the Donation Edition, while the Business Edition is licensed for commercial use with device-based licensing and reseller options.
