In previously highlighted issues regarding backing-up shared documents to my Seagate Freeagent hard drive, I simply decided to move the My Music Folder from the shared documents folder, but Windows is disallowing me from doing this stating that My Music is a Windows system folder & cannot be renamed or removed? Any help please on getting around this to move My Music from the shared documents? I'm running XP with servce pack 3.
