I've currently got two hard drives in my system (C: and D. I've set the My Documents property value to point to the D: drive so everything in My Documents gets put onto the second drive. That also contains all my app installers. I will need to effectively reformat my C: drive to put Vista on it over the next few weeks. Apart from my Outlook local folders file, is there anything that I should back up from the C: drive? Perhaps the Documents and Settings folder (for my Favourites)?
