DAEMON Tools Pro is a virtual DVD-ROM emulator based on a SCSI miniport driver. It emulates max. 4 DVD-ROM drives and works with CD/DVD images created by many burning programs. It is great on notebooks without a physical CD-/DVD-ROM drive or to save akku power and speed up CD/DVD access. In opposite to other CD-/DVD-ROM emulators DAEMON Tools Pro doesn't use a proprietary container format.
The advantage is that you can can burn the images you're using with DAEMON Tools Lite Pro away or just test an image before burning it to see if it was created correctly. DAEMON Tools Lite works with most image formats. It supports Alcohol 52/120%-Images (MDS-Files) and RMPS-Media!
