Windows user may not be aware of what kind of file with the .dmg extension and how to open it. This will be discussed in this small instruction.

A DMG file is a disk image in Mac OS X (similar to ISO) and its opening is not supported in any existing version of Windows. In OS X, these files are mounted by simply double clicking on the file. However, access to DMG content is also possible in Windows.

Simple DMG discovery with 7-zip

The free 7-Zip archiver can, among other things, open DMG files. Only extracting contained files from the image is supported (you cannot mount a disk, convert it or add files). However, for most tasks, when you need to view the contents of a DMG, 7-Zip is fine. Just select in the main menu File - Open and specify the path to the file.

Here's a short guide on opening DMG files on Windows and extracting data from them. Once Z-7ip is installed, find the DMG file you want to work with in File Explorer and right-click on it. In this case we're using some of Apple's free system fonts as an example.

Convert DMG to ISO

If you have a Mac computer, then in order to convert the DMG format to ISO, you can simply execute the command in the terminal:

hdiutil convert путь-к-файлу.dmg -format UDTO -o путь-к-файлу.iso

For Windows, there are also programs converters DMG to ISO:

  • Magic ISO Maker is a freeware program that has not been updated since 2010, which, however, allows you to convert DMG to ISO format http://www.magiciso.com/download.htm.
  • AnyToISO - allows you to extract the contents or convert almost any disk image to ISO. The free version limits the size to 870 MB. Download here: http://www.crystalidea.com/ru/anytoiso
  • UltraISO - a popular program for working with images allows, among other things, to convert DMG to another format. (Not free)

In fact, there are still a dozen disk image conversion utilities on the Internet, but almost all the ones I found showed the presence of unwanted software in VirusTotal, and therefore I decided to limit myself to those mentioned above.

Other ways to open a DMG file

And finally, if 7-Zip didn’t suit you for some reason, I’ll list a few more programs for opening DMG files:

  • DMG Extractor - formerly a completely free program that allows you to quickly extract the contents of a DMG file. Now on the official website there are two versions and the main limitation of the free one is that it works with files no larger than 4 GB.
  • HFSExplorer - this free utility allows you to browse the contents of disks with the HFS + file system used on Mac and with its help you can also open DMG files with no size limit. However, the program requires Java Runtime on the computer. Official site http://www.catacombae.org/hfsexplorer/. By the way, they also have a Java utility for easy DMG extraction.
