A Virtual Floppy Disk is a disk image stored as a file on your computer's hard drive. It is a substitute to the traditional floppy drive, with the exception that it exists as a file rather than a physical media that conventional floppy drives have been. As the word “virtual” suggests, a virtual floppy disk works as a disk image stored as a file on the hard disk with the same drive letter - A. It works in the same way as a CD, DVD or ISO image file. You create or download a virtual copy of a Floppy and mount it.
