In WinXP Pro, I can designate the "My Documents" folder in my main drive as "Private" (i.e. not accessible to other users who login to this same machine). How can I designate other drives or folders in another drive as "Private"? All my drives are NTFS formatted. I'd like to use my second drive as backup for my "My Documents" but am concerned that access on the second drive is not restricted to other users logging in to this same machine.
