The free Lite version of Daemon Tools lets you create virtual CD, DVD or Blu-ray drives as well as ISO and MDS images. After you've installed it, Daemon Tools Lite will be in the system tray. When you click on the icon, you can determine from which images you'd like to create virtual drives. Then there will be a new drive letter in Explorer that fulfils the same tasks as a physical drive.
As well as CD and DVD copies the program supports images of modern blu-rays. Because the images need a lot of space, a big hard drive is necessary. You can create up to four virtual drives at the same with with the Lite Version. The paid for pro version lets you emulate up to 32 drives.
Another feature is the creation of physical CD, DVD and blu-ray drives from original ISO/MDS images. If you want to protect the content, you can set a password to prevent unauthorised access of the images. The pro version can even create ISO images from CDs and DVDs, which you can then burn or mount.
Verdict: Daemon Tools Lite is enough for the private user in most cases. You will save yourself the constant insertion of often used discs.
Note: The test version is only intended for legal copies in consideration of current copyright laws. Copying without the approval of the content creator is illegal.
During the installation you should untick various boxes, which would enable the tool to hook itself into the system and upload additional software to your computer. You should also choose the free license in one of the installation steps.
