Visual Subst can associate any folder with a virtual hard drive in order to make it readily accessible in My Computer.

If you frequently work with a folder or folders that are buried deep within your system’s folder hierarchy you can use Visual Subst to associate said folder with a virtual drive, (”x:”, for example).

The program does not actually change the location of your folder (it is still in its original location and can be navigated to from the folder structure). Also, the virtual drive can be easily removed at any point.
