Open DMG File on Windows, Mac OS, Android

DMG is used for disk image files on Macintosh computers running Mac OS X. This file extension replaces the older file extension IMG which was discontinued during the release of later series of Mac operating systems. You can open DMG file on Mac, Linux, and Windows operating systems but it will require additional software to be installed on Windows. Note that on Windows and Linux you cannot open every DMG file, since there are certain software limitations on DMG format variation.

DMG files are used by Apple for software distribution over the internet. These files provide features such as compression and password protection which are not common to other forms of software distribution file formats. DMG files are native to Mac OS X and are structured according to Universal Disk Image Format (UDIF) and the New Disk Image Format (NDIF). They can be accessed through the Mac OS Finder application by either launching the DMG file or mounting it as a drive.

DMG is also referred to as the Apple’s equivalent to MSI files in Windows PC. Non-Macintosh systems may access DMG files and extract or convert them to ISO image files for burning. Several applications are designed to offer this solution for Windows systems.

7-Zip and DMG Extractor are the best options to open DMG file on Windows because they are compatible with the most DMG variations. For Linux a built-in "cdrecord" command can be issued to burn DMG files to CD's or DVD's.
