These files can be created with Disk Copy, burned to a CD or even mounted as a normal volume on Macintosh computers. They often contain raw blocks of data that are usually compressed for easier file management.

Some .dmg files may be encrypted in addition to being compressed, for added file security. These files are often used by software installers that download applications from the Internet to a user's computer.
