How to open DMG files

Here's a short guide on opening DMG files on Windows -- and extracting data from them.

  1. Download the free DMG Extractor.

  2. Open DMG Extractor and select the DMG file you want to extract

    Click the "Open" menu icon on the top-left of the window.

  3. Select the DMG file you want to extract

    If the DMG archive is password protected, DMG Extractor will prompt you for its password:

    After doing this, DMG Extractor will load the file you selected. If you have a large DMG file, a progress bar will show until the DMG file is loaded.

    Now you should be able to see all the files contained within the DMG file and navigate folders and files.

  4. Extract the files you want

    Click "Extract", next to the "Open" button. You can choose whether to extract the whole of the DMG's contents into the same folder, or into a specific one chosen by you. If you don't need to extract all the files, just select the files you want and on the "Extract" menu click "Selected files to…"

That's it -- extraction complete! Your selected files should now have been converted from the DMG file and saved onto your Windows computer ready for you to use.

DMG Extractor supports 4GB+, FAT and ex-FAT DMG images, too
