Not all computers have a CD or DVD unit, and it can happen that you don't have an optic disc on which to record contents. And that is the precise moment in which Daemon Tools really makes sense: a virtualization tool with which you will be able to mount up to 4 virtual drives and thus emulate devices that aren't really on the computer.
Thanks to Daemon Tools you will be able to emulate CD and DVD drives on your computer and read disc images as if they were real discs, treating them in a way that is similar to using a traditional disc reader. Daemon Tools is, without any doubt, one of the best applications for Windows for this purpose, in great part due to its flexibility and to its complete personal configuration options.
One of the optical support emulation programs available.
If you don't have an optical disc reader, but you aren't resigned to stop using disc images, Daemon Tools is the solution. Virtualize up to four different tools making the most of an essential application for your PC.
