vSubst is a small tool that allows you to creates drive-letters for any folder on your hard disk. For example , you can take folder X and make it look and feel as if it was Drive X. This can be very useful if you need to simulate certain environments or want to create a virtual CD drive. There are certain restrictions, you obviously cannot defrag or format the folder as if it was a real drive, but other than that, Windows thinks it's the "real thing". You can choose to create the drives temporarily or permanently.
