Best Free Sync Software

File synchronization software helps keep updated copies of files and folders in two or more locations, such as different computers, network drives, USB drives, or online storage.

While a file sync utility could be used as a simple backup tool (one-way syncing), its real power lies in keeping an identical set of working files in two or more locations (two-way syncing), such as keeping current versions of the same files on both your home and office computers.
