I had known for a while that as of Windows 2000 there was a way to create what I called a Drive Shortcut but I never could find the documentation on how to actually do it. It turns out this was included in the resource kit which is probably why i never stumbled across it. But I still get asked on a regular basis if it is possible to map a specific folder location to a logical drive letter similar to the way you map a networked share. The idea being that it would look like any other drive except it would actually point to a much longer or obscure physical mapping. Well I just saw a post from Mark Russinovich that talks about his utility called Junction that allows you to do this very easily without the resource kit. Windows Vista has a neat little feature in the Windows Explorer that allows you to map folder locations as a favorite but from what I can see you still need something like this to make it visable from other places outside Windows Explorer as well.
