ShrinkWrap™ is a drag and drop utility for handling all types of disks and disk image files. Drag your image files into the application and ShrinkWrap™ will automatically mount the image in your desktop.

I case you don't know what a disk image is, it is a file that has all the information contained in it to make a EXACT duplicate of a disk, mainly for backup purposes. This exact duplication will alleviate some of the installation problems with some installers which demand the original program disk.
