While there are a couple of handy options out there to open or extract a DMG file in Windows, we will share the best three tools to deal with DMG files in Windows environment.


DMG Extractor

DMG Extractor is probably the first and only tool designed exclusively to deal with DMG files in Windows. Since DMG Extractor is developed specially for DMG files, it can open encrypted .DMG files without having to first convert them to other formats.

Using DMG Extractor is fairly simple. After installing the software, right-click on the DMG file that you want to open and then click Open option to open the file with DMG Extractor. Alternatively, after launching DMG Extractor, click Open button and then select the DMG file to contents of the selected DMG file.

To extract a DMG file, click the Extract button and then select a location to save the contents.

Another free utility that you can install on your Windows machine to extract DMG files is HFS+ Explorer. With HFSExplorer you can open Mac-formatted disks and disk images in Windows.

While HFSExplorer is relatively easy-to-use, we must mention that it’s not as straight-forward as DMG Extractor. You need to install Java SE Runtime Environment 5.0 or above in order to run HFSExplorer and it doesn’t support all type of DMG format, including DMG UDF format.

Step 2: Visit this page to download HFSExplorer and run the installer to get it installed.

Step 3: Run HFSExplorer, click File menu, and click Load file system from path option to browse to the DMF file.
