If you get access denied errors, you may have to take ownership of the folders. Log on as Administrator (if you are running XP Home boot to safe mode). Open Folder Options and disable "simple file sharing"(Last option on the view tab). Next right click the drive or the folders you can't access in explorer > sharing and security > security > advanced > owner. Change the owner to your username and check "replace owner on subcontainers and objects". Last reenable simple file sharing again.
