Trying to open a DMG file on Windows can feel a bit like trying to fit a square peg in a round hole—because technically, these files are designed for Macs. They’re like little locked boxes carrying data meant for MacOS, and Windows doesn’t recognize them by default. So, if you’ve got one and need to peek inside, you’ll need a helper—some software that can read, unpack, or at least extract files from DMGs. The good news is, with a few tools, it’s pretty straightforward, even if it’s not always as smooth as opening a ZIP. Sometimes, it’s a bit of trial and error, and some programs work better than others depending on the file’s complexity. This guide is about showing how to get around that. The goal: open or extract those Mac files without having to switch to a Mac. You get to see inside the DMG, grab whatever files you need, and move on with your life—no need to dual-boot or run a virtual machine or something weird. Just some software, a couple clicks, and you’re good to go.
How to Open DMG File on Windows
Method 1: Use 7-Zip
7-Zip is kind of the unsung hero here. It’s free, open-source, and handles a bunch of archive formats, including DMG files, surprisingly well. The reason it helps is that it can see into those Mac disk images and give you access to the content—you don’t necessarily get a pretty drive or mount it like on a Mac, but you can see and copy files. This method’s perfect if your DMG isn’t encrypted or specially formatted. Also, on some setups, 7-Zip might be a little flaky or not handle certain encrypted DMGs, but for most casual stuff, it just works. First, head over to the official 7-Zip site and download it—pick the right version for your Windows. It’s usually straightforward, just download the installer and run it. Installing is easy—click through the default options. Once installed, locate your DMG file in File Explorer. Next, right-click on the DMG file, hover over “Open with”, and select 7-Zip. Sometimes, you might need to click “Choose another app” if it’s not immediately listed, then find 7-Zip from the list or browse for it in `C:\Program Files\7-Zip\7zFM.exe`. If everything’s working right, you’ll see a window pop-up with the folder view of contents inside the DMG. To actually get the files out, select all the items inside, then click on “Extract” in 7-Zip’s toolbar. Choose a destination folder—say, your Desktop or Downloads—and hit OK. After that, you’ll have the files extracted and ready to use. Keep in mind, on some machines, the first try might not work perfectly—sometimes you gotta restart 7-Zip or give it a couple tries.
Method 2: Try DMG Extractor or PowerISO
If 7-Zip doesn’t do the trick, another one to try is DMG Extractor. It’s paid but has a free version for smaller files, and it’s pretty user-friendly. Same idea: load the DMG, extract files. Sometimes it handles encrypted or tricky DMGs better, but it’s not free forever.DMG Extractor is a solid choice.
Another alternative is PowerISO, which is commercial but often offers trial versions. It can open DMG files and mount them as virtual drives so you can browse as if you plugged in a Mac disk. That’s handy if you want to explore without extracting.
Tips for Opening DMG Files on Windows
- Stick to trusted programs like 7-Zip or DMG Extractor—avoids security nastiness.
- Always verify where you’re grabbing the DMG from—some shady sources may carry malware.
- Update your software regularly—older versions might struggle with newer DMGs.
- If one tool refuses to open a DMG, try another—different tools have different strengths.
- Watch out for executable files inside; malware could hide in there.

Other options besides 7-Zip?
