FreeFileSync
Freeware file synchronization program
From Wikipedia, the free encyclopedia
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.[2] FreeFileSync has received positive reviews.[3][4] 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.
Adware/malware
Earlier versions were packaged with OpenCandy,[5][6] an adware module which many antivirus software vendors classify as malware.[7][8][9][10]
Since the release of version 10.0 in April 2018, the software is ad-free.[11] In November 2018 Norton wrongly identified the FreeFileSync installer as malware and blocked its execution.[12]
