ownCloudSync folder synchronization - libraries
The ownCloudSync system lets you always have your latest files wherever you are. Just specify one or more folders on the local machine to and a server to synchronize to. You can configure more computers to synchronize to the same server and any change to the files on one computer will silently and reliably flow across to every other. . This library is based on CSync, but adds functions that are missing in CSync and more specific to graphical clients.
