you are referring to.
If you are referring to the Application VIRTUAL DRIVE for creating virtual CD drives on a hard drive check here:
If you are referring to a Virtual drive on a virtual PC for installing and running other Operating Systems under a Host OS then look up Microsoft Virtual PC or VMWare.
Then too, a RAM drive would be another type of Virtual Drive.

What is a virtual drive and how does it function?
If i want to install this drive, what should i do?
