Recently used files are available offline. However, to ensure the files and folders you need are available when you are offline, whether they have been accessed recently or not, you need to identify them to Xythos Drive cache. You can choose to have Xythos Drive synchronize these files when you connect to and/or disconnect from the server. 

Xythos takes care of keeping files selected to be available offline synchronized between your local PC and your account. By default, synchronization will occur when you connect and when you disconnect.

Use the features available on this tab to select the files you want to use offline, to synchronize your offline files with the files on the server, and to select when you want synchronizations to occur.

Synchronization Options

On connection	If selected, when you connect online Xythos Drive synchronizes the local copies of offline files with the corresponding files on the server. By default, this option is selected.
On disconnection	If selected, when you disconnect Xythos Drive synchronizes the local copies of offline files with the corresponding files on the server. To end a connection, press the Disconnect button on the Connect tab, or in Windows Explorer, right-click the mapped drive and select Disconnect. When you exit Xythos Drive all connected services are disconnected and no synchronization occurs, regardless of this setting. By default, this option is selected.
Note: If neither of these settings is selected, your files will not be synchronized.
Synchronize Now	Click this button to immediately synchronize the local copies files selected as always available offline with the corresponding files on the server.
