The Syncplicity client will sync any local, internal drive on your PC or Mac. It will not sync network drives or other external storage devices connected to your system.
For accessing network data Syncplicity provides the Panorama connector. It does not require that your IT person move the data. Panorama is available for Enterprise Edition Syncplicity accounts.
Information about Panorama is available here, including the supported platforms and requirements:
