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:

    DMG extractor encrypted file

    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.

    open 4gb dmg file

    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

why would not open 4gb larger dmg file in DMG Extractor. please send your suggestion. how could open the file.OS X 10.8 Mountain Lion Golden Master .

Yes, have a 13 Gig DMG file, but cant open with current DMG Extractor

I need to extract a very large .dmg (1.2 Tb) which is corrupted, and won't open in Mac OS! I was hoping to salvage some with a DMG extractor. Help!

we need a convertor to files more than 4 GB

y can't we extract files more than 4 gb. This really sucks and i'm disappointed.please find a solution and hurry!!!!!!!!!!!!

i want to extract 6.27gb file;how?

i want dmg extractor to extract files larger than 4gb

all of the mac os x install images (leopard, snow leopard, lion, mountain lion) are all greater than 4GB in size and thus your tools cannot be used.

It would be better if files larger than 4gb could be extracted too.

hi I have a 4+ GB dmg. is it possible to open it with this software? many thanks!

Absolutely, yes!
