Sync Center displays your sync results if you've set up your computer to sync files with a network server. This allows you to access files stored in a network folder, even when that folder is unavailable by making it available offline.
Open Sync Center by clicking the Start button . In the search box, type Sync Center, and then, in the list of results, click Sync Center.
Sync Center can't be used to sync devices with your computer. For information about that, see Sync music, pictures, contacts, and calendars with a mobile device.
