A DMG file is a mountable disk image used to distribute software to the macOS operating system. The file is typically downloaded from the Internet by a Mac user, then double-clicked to install an application on the computer.

Today, software developers typically build and distribute applications for Mac users as DMG, .APP, or .PKG files. DMG files are especially common since their contents can be verified upon installation to ensure they have not been tampered with and they can also be compressed to reduce the size of the installer.

When a Mac user downloads a DMG file, he can simply double-click it to open it with the DiskImageMounter utility that comes with macOS. When the DMG file is opened, it mounts a virtual disk on the desktop and in an Apple Finder window as if it was a CD or a USB flash drive that was just inserted into the computer.

In the Finder window, the Mac user can double-click the program icon, which is an APP file, to run the app. Or the Mac user can drag the program icon to the 'Applications' folder icon to move it to the 'Applications' directory in macOS.

After the software stored in the DMG file is installed, the DMG file is no longer needed. Therefore, DMG files can be deleted after installing the software.

While DMG files are Mac-specific and not intended for use in Windows, there are several Windows programs that can extract their contents or convert them to other formats. Some programs include 7-Zip, PeaZip, and DMG2IMG.

NOTE: The DMG format replaced the .IMG file format, which was previously used in Mac OS Classic.

extension. These DMG files are Apple Disk Image containers that are used in macOS to distribute software or files. While a Windows user likely won’t have use for a DMG file containing a macOS application installer, in the cases where a DMG simply contains files — such as fonts, images, or documents — it may be necessary to open it. If you have access to a Mac, you can simply open the DMG file there and then transfer the extracted files to your Windows PC. If you don’t have a Mac, you can still open the file in Windows, but you’ll need third party software to do so. There are several third party utilities that can open a DMG file in Windows, but one of the easiest is 7-Zip, the free and open-source file archive utility. 7-Zip is one of the first applications we install on new Windows installations for its robust handling of ZIP and RAR archives, so you may already have it installed by the time you need to open a DMG file in Windows.

Open a DMG File in Windows With 7-Zip

1. If necessary, head over the 7-Zip website to download and install the applicable installer. There are different versions depending on your version of Windows (32 or 64-bit) and installer type (executable (exe), Microsoft Installer Package (msi), or a 7-Zip archive (7z).
2. Once the utility has been installed, open Windows File Explorer and locate the DMG file. Right-click on the DMG file and you’ll see a 7-Zip command in the menu. Hover your mouse cursor over 7-Zip to reveal the sub-menu of applicable commands.
3. Select the desired command depending on what you want to do with the DMG file. Selecting Open lets you see the contents of the DMG file in the 7-Zip archive browser without actually extracting them. Selecting one of the Extract commands will extract the DMG contents, either to the current folder (Extract Here), to a new folder with the same name as the DMG file (Extract to…), or to a custom location you can define (Extract files…).
4. Any of these options will give you access to the contents of the DMG file. Note that you will likely see a number of extra folders related to metadata and indexing. These are used by macOS but, due to the different ways that macOS and and Windows handle hidden files, you’ll only see them in Windows. In general you can ignore these extra files and navigate the file or folder structure to find the core files you’re looking for.

Note that 7-Zip does not let you create DMG files in Windows. However, if your intent is to simply share an assortment of documents or media files with Mac users, you can just use a ZIP file, which is natively supported in macOS.
