Virtual CloneDrive works and behaves just like a physical CD/DVD drive, however it exists only virtually. Image files generated with CloneDVD or CloneCD can be mounted onto a virtual drive from your hard-disk or from a network drive and used in the same manner as inserting them into a normal CD/DVD drive.
Features:
Supports all common image formats such as ISO, BIN, CCD
Supports upto 8 virtual drives at the same time
Easy to use - just double-click an image file to mount as a drive
