What is a .DMG file?

dmg file icon

DMG files contain compressed software installers that are used in the distribution and installation of applications in macOS. The files replaced IMG files when Mac OS X was released in 2001 and are still commonly used today. macOS users download DMG files from the Internet, then double-click them to begin the installation of a program. When a DMG file is opened, it mounts a virtual disk on the desktop to install the program.

Typically, Windows users won't encounter DMG files since they are specific to Macs. However, File Viewer Plus can be used to extract the contents of a DMG file, much like a ZIP archive. This feature is especially useful for anyone looking to examine or modify the contents of a DMG file.
