Features are definitely not lacking in the full Alcohol 120% program. At its core, Alcohol 120% is an advanced CD/DVD backup utility, designed to protect your original copies of any CDs or DVDs. But it’s known for much more. In addition to standard copying, Alcohol 120% allows you to not just copy to another CD or DVD, but also to copy the complete image directly to your hard drive.
The program also includes a virtual drive emulator. What that does is allow the software to create a fake CD/DVD drive, which can then load the CD/DVD image file you backed up and then treat it as if you had the actual CD/DVD in the drive. While there are other software titles available that do this, Alcohol 120% allows for an unprecedented number of virtual drives--31! That means that you could backup 31 game disks, load a virtual drive for each one, and then switch among all your games without having to get up to find the CD binder where you left them. It’s an extreme convenience, especially as you consider the games that contain multiple CDs or DVDs, which interrupt your gameplay.
You can create or delete the images as you need, and can of course back them up on disk as well, if you are running out of space. You can also access those image files across your network, which comes in handy for teachers or employers, or anyone who is tired of remembering to take an installation CD from computer to computer.
The only current limitation I could find with Alcohol 120% is the inability to image or copy high definition disks, Blu-Ray and HD-DVD. Although there are no other software titles I am aware of that allow you to image these types of disks, there are applications available that allow for copying them.
