How to Open and View DMG File on Windows 10/8/7

I believe that most Windows users have encountered such a problem that you cannot open .dmg files on Windows computers, also you cannot view or extract anything in a DMG files. That’s because DMG file is just a "distribution" format that is natively used to distribute installation packages for Mac OS, Therefore, DMG file is not natively supported by Microsoft Windows OS, it was like the .exe file on a Windows computer.


On the Mac OS, DMG file actually contains Mac OS installation files and software programs that can be used on macOS. It’s the best Apple format files since it can’t be tampered while it’s also a unique Mac standardized file format certified by Apple. Since this is a distribution file format it allows users to stretch, encrypt and compress of the file, so some you may find some DMG files are encrypted. Much of the time when we need to open a DMG file and view its content on a Windows computer, what should I do? In principle, in order to open .dmg file on a Windows computer you will need to special software that can recognize this format.

Open DMG File on Windows using 7-ZIP

The first solution I’d like to recommend is 7-Zip, which is an open-source utility that can be used to open a .dmg file in Windows 10/8/7 without damaging original data. The zip’s application is similar to a file explorer, that means when you open a .dmg file on ZIP you can browse all content in a DMG file with 7-zip user interface.

 

Step 1. Supposed that you’ve installed 7-ZIP on your Window computer, then launch it. Click Add button to load your .dmg file.

 

Step 2. Once your dmg file is loaded then 7-Zip will open your DMG file on Windows 10, while it will show file sizes, created, modified and accessed dates for all files in DMG archive. You will be able to see what is inside it.

Open DMG File by Converting DMG to ISO

Converting DMG to ISO is a clumsy way that also can be used to open and view content of Mac on a Windows computer, Although a lot of times it does works but this makes you detours! You will need a ISO conversion tool like AnytoISO or WinArchiver or other ISO program that allows you to mount it as normal. However, most ISO conversion are not free, so you may be asked to purchase a full version or upgrade in order to convert DMG files.

 

But dmg2iso is a freeware whose sole purpose is to create ISO images from compressed DMG file. The only drawback is that it’s a standard command-line utility that provides graphical interfaces.

 

Step 1. first of all, download the dmg2iso utility on its site. http://vu1tur.eu.org/tools/, then extract the files of dmg2img to a new folder.

 

Step 2. In your Windows 10 computer, open a command prompt with admin, then use the cd command to navigate to the folder where you extracted dmg2img.

 

Step 3. type the following command to convert your DMG file.

 

dmg2img.exe {source file.dmg} {destination file.iso}

Step 4. Waiting for it to be done, then you will get a ISO files and you check mount it with your Windows 10.
