Note: To quickly access the Application Data folder, click Start, and choose Run. Type %appdata% and clickOK.

Note: To quickly access the AppData folder, click Start. In the search bar, type %appdata% and press the Return key.
Thanks John Galt. This solved my problem becuase you provided a way to access AppData using the Start search box. From there I was able to follow the path you listed above ...\Roaming\Apple Computer\MobileSync\Backup. That made a difference from the first suggestion. Thanks for providing both answers.
