Opening DMG files
Did your computer fail to open a DMG file? We explain what DMG files are and recommend software that we know can open or convert your DMG files.
What is a DMG file?
DMG files are files that are treated like actual hard disks by the Macintosh OS X operating system. 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.
The Oracle export and import utility, used by Oracle databases, also uses the .dmg file extension for database dump files that are stored a binary file format.
