FreeFileSync is a program used for file synchronization. It is available on Windows, Linux and macOS. The project is backed by donations. Donors get access to a Donation Edition that contains a few additional features such as an auto-updater, parallel sync, portable version, and silent installation.[1] FreeFileSync has received positive reviews.[2][3] FreeFileSync is available free of charge for personal use; the official Windows installer requires the users to accept the terms of use, which state that for business use they are required to purchase a business edition version of the application.
FreeFileSync works by comparing one or multiple folders on their content, date or file size and subsequently synchronizing the content according to user-defined settings. In addition to supporting local file systems and network shares, FreeFileSync is able to sync to Google Drive, FTP, FTPS, SFTP and MTP devices.
Earlier versions were packaged with OpenCandy,[4][5] an adware module which many antivirus software vendors classify as malware.[6][7][8][9]
Since the release of version 10.0 in April 2018, the software is ad-free.[10] In November 2018 Norton wrongly considered FreeFileSync installer as a malware and blocked its installation.[11]
FreeFileSync is available for 32bit and 64bit operating systems. As of July 2024 the then current version 13.7 of FreeFileSync supported the following operating systems and versions:[12]
Support for Windows Vista and XP ended with FreeFileSync_v10.11. The latest release compatible with Mac OS X 10.7.5 is FreeFileSync_8.4_Mac_OS_X. Older versions are still available on the project website.[13]
