Daemon Tools Lite is a well known utility that can emulate CDs and DVDs using virtual units. This capacity enables you, for example to watch a movie, listen to a music album or copy data from a CD/DVD without inserting their corresponding discs.

It can emulate up to four virtual units and upload ISO, CUE, CCD, CDI and MDS image files to them, among other image formats. Those images are exact copies of any disc and will be mounted until you determine so.

Daemon Tools Lite can also be used to test an image content before you burn it to a CD/DVD, in such a way that you can make the necessary changes before creating the disc. The application can emulate different copy protections, such as Safedisc, which is one of the most spread copy protections.
