File Extension DMG

Definition

A file with the extension .dmg (an abbreviation for disk image) uses a disk image format commonly found on Mac OS X. The format allows secure password protection as well as file compression and hence serves both security and file distribution functions. Its most common function is the distribution of software over the Internet. When opened, DMG files are mounted as a drive within the Finder. DMG files can be easily created (with or without encryption) using utilities that are included in OS X: Disk Utility in Mac OS X v.10.5, Mac OS X v10.4 and 10.3 or Disk Copy in earlier versions. These utilities also use DMG files as images for burning CDs and DVDs. DMG files may also be managed via the command line using the hdiutil utility.

Windows Cannot Open DMG Files?

If Windows cannot open DMG files you may not have the appropriate program installed or have a registry related error. We strongly recommend you run a free registry scan.

Computers perform best when they receive regular, professional maintenance. The installation and un-installation of software, hardware, and drivers often leave remnants behind in your registry, resulting in a tangle of unused applications, broken drivers, and incomplete and empty command signals. This mass of confusion slows down your computer and if not addressed promptly can lead to serious problems such as computer not recognizing file extensions, freezing, programs not responding, and system crashes.
