GoodSync can update and back-up files over a local network or the Internet.GoodSync can detect when just the time or state of a file has been changed and modify it on the other side, without copying the entire file.

Can automatically keep backups of old files that are deleted/overwritten.

Like SuperFlexible file synchronizer, Allway sync and Unison, it has the capability to remember the previous state of directories in a database, and thus also propagate deletions.

A tree view of the intended synchronization, with many views such as files to overwrite, files to delete, files with same length, but different time and excluded files.

It detects 'conflicts' where a file has been modified on both sources, and displays these to the user.File masks and filters allow the user to define exactly what files and folders to include and ignore.In other words, when two devices are synchronized, the user can be sure that the most current version of a file is available on both devices, regardless of where it was last modified. GoodSync allows the same version of files to be maintained on multiple computing devices.
