Desktop and Mobile Synchronization
Syncronizing files with your desktop computer is easiest with the Desktop Synchronisation Client. While it is not mandatory, it eases keeping files in sync a lot. See the download link ownCloud Sync Client for Windows, Mac OS X and Linux clients.
The ownCloud Desktop Sync Client enables you to connect to your private ownCloud Server. You can create folders in your home directory, and keep the contents of those folders synced with your ownCloud server. Simply copy a file into the directory and the ownCloud desktop client does the rest. Make a change to the files on one computer, it will flow across the others using these desktop sync clients. You will always have your latest files with you wherever you are.
Its usage is documented separately in the ownCloud Desktop Client Manual.
