I have a directory on another drive that I want to show as a new virtual drive. How can I do that?

Use the subst command:

subst X: F:\some\folder

There is also a great freeware utility called Visual Subst to make things even easier:

yes I tried this before, but it doesnt auto-mount the dir on boot. –  user11955 Feb 16 '10 at 4:20

At the bottom of the application there is a checkbox Apply virtual drives on Windows startup if that's what you're after. You could also use a batch script with subst commands and place it in your startup folder. –  John T Feb 16 '10 at 4:24

I realize that the option is there, it just doesn't work. probably because I have a space in the folder name (that I cant remove) –  user11955 Feb 16 '10 at 4:30

Possibly. There is also the startup folder in your start menu you can use. Make a batch script with subst commands in it and quote the paths with spaces. An example of 1 line would be subst X: "C:\Program Files" –  John T Feb 16 '10 at 4:31
    
Or add it as a run entry in the registry. It gets processed and the subst drive gets added quite early in the boot process then. –  Fiasco Labs Oct 1 '12 at 15:31
