How To Open A .dmg File On Windows 10

Sep 07, 2019  Double-clicking a DMG file on a Windows computer will prompt you to select a program with which to open the file. Unless you have a third-party tool like 7-Zip or DMG Extractor installed on your computer, you won't be able to open the DMG file. According to the Wikipedia page on DMGs. In Windows, most dmg images can be opened using several other programs such as Acute Systems TransMac, HFSExplorer, 7-Zip, UltraISO or IsoBuster.MacDrive9 can also mount simple dmg files as drives under windows, but not sparse disk or encrypted dmgs. Very simple, use 7-Zip and DMG Extractor. Either should do, I would prefer first one. Here’s how to extract content from a DMG in Windows 10. The best option, whenever possible, is using 7-Zip. You probably already have it if you’re a Windows regular, since it’s a free and convenient way of extracting the more universal ZIP format. Windows operating system doesn’t support DMG files out of the box and we need to take the help of third-party tools to open DMG files in Windows. If you have a DMG file and want to convert the same to ISO on a computer running Windows operating system, there are plenty of ways to do it.

Every so often you are sent a file that has a generic icon on it, and no software on your PC can open it. You check the file extension, and it is .DMG. A .DMG file is a Mac Disk Image. There are different software options that can read and extract the contents of .DMG files so you can access the files within.

7-Zip Method

How To Open .dmg Extension File In Windows 10

Step 1

Download the 7-Zip installer package, and install it on your computer.

Step 2

Run 7-Zip once the installation is done. Navigate to 'Tools > Options....' Click 'Select All' unless there are specific file formats listed that you require to stay registered with a different program. Click 'Apply' and then 'OK' when you are done.

Double-click the .DMG archive to open it. You can now extract the contents of Mac .DMG files.

AnyToISO Method

Step 1

Step 2

Run the installer and select your desired installation location. Run AnyToISO once the installation is complete.

Click 'Browse...' and select your source .DMG file. Click 'Convert.' You now have a PC-compatible .ISO image that can be burned to a CD and read.

DMGExtractor Method

Step 1

Download the latest DMGExtractor standalone .JAR (Java ARchive) file.

Step 2

Place the .JAR file where you want it to be installed, e.g., 'C:Program FilesDMGExtractor.'

Double-click the .JAR file. Click 'OK' on the first pop-up. When prompted, click 'No' if you only wish to do error checking on the .DMG file. Click 'Yes' if you wish to convert the .DMG file to an .ISO file. Navigate to the folder with the .DMG. Specify the output name (DMGExtractor defaults to the same name as the .DMG file) and click 'Save.' You now have a PC-compatible .ISO file that can be burned to a CD for reading on a PC.


  • Using 7-Zip is the easiest method of the three outlined here, because it actually extracts the contents of .DMG files, whereas all other programs merely convert it to an .ISO, which has to be burned to a CD to be read. 7-Zip can also extract .ISO files.
