title: What protocol does RDP on Windows 7 use for copying files via the clipboard?
body: <p>When I copy a local file and paste it to a remote computer through an RDP session (both clients are Windows 7) is it transferring the file data via SMB, SFTP, or some other protocol/port?  I've poked around the RDP GUI and don't see any clear reference to clipboard transfer protocols or ports.  Just curious.</p>
