Universal Disk Image Format (UDIF) is the native disk image format for Mac OS X. Disk images in this format typically have a .dmg extension. New Disk Image Format (NDIF) was the previous default disk image format in Mac OS 9, and disk images with this format generally have a .img (not to be confused with raw .img disk image files) or .smi file extension. Files with the .smi extension are actually applications that mount an embedded disk image, thus a 'Self Mounting Image', and are intended only for Mac OS 9 and earlier. A previous version of the format, intended only for floppy disk images, is usually referred to as 'Disk Copy 4.2' format, after the version of the Disk Copy utility that was used to handle these images. A similar format that supported compression of floppy disk images is called DART. Apple disk image files are published with a MIME type of application/x-apple-diskimage.

Different file systems can be contained inside these disk images, and there is also support for creating hybrid optical media images that contain multiple file systems. Some of the file systems supported include Hierarchical File System (HFS), HFS Plus, File Allocation Table (FAT), ISO9660 and Universal Disk Format (UDF).

Open DMG File

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.
