File Synchronization is an utility that, as its name implies, has the ability to synchronize multiple pairs of folders or files. It has been designed to be easy to use and quick to do the job. It was based originally on the File Synchronization tool provided by Apple with the old Mac OS, but has a few improvements and features to help get the job done quickly and efficiently.
