Virtual CloneDrive allows you to create up to eight virtual drives, which you can use just as your physical CD or DVD drives. This gives the option to open, browse and use compressed image files “on the fly,” without having to decompress them to your hard drive first. The supported image file formats are ISO, BIN, and CCD and they can reside on the hard drive or a network drive. The speed of this free application is quite impressive and Virtual CloneDrive is also extremely easy to use.
