Insert the flash drive into the USB port of a Mac computer that has the DMG file you need. Launch Finder. After a couple of seconds the drive appears in the left menu of the Finder menu. If Mac OS X doesn't recognize the flash drive, it prompts you to format it and the Disk Utility app opens.

None of the versions of Windows operating system supports DMG format out of the box. As you likely know, DMG file is an OS X disk image file and are supported in Mac OS X operating system. One needs to take the help of third-party tools in order to open a DMG file on a PC running Windows operating system.

Dmg File Mac

Those of you have spent considerable amount of time on Mac would know that the DMG is mostly used to install apps on Mac. In other words, apps that we download to install on a Mac OS X use .DMG extension and can be mounted easily by double-clicking on the file on Mac.

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 on Windows OS. Since DMG Extractor is developed specially for DMG files, it can open encrypted .DMG files without having to first convert them to other formats.

Raw, Bzip2, Zlib, and Zero block type DMG files are supported by DMG Extractor.

The only catch with the free version of DMG Extractor is that it can’t open DMG file of size more than 4GB but that shouldn’t be problem for most users.

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.

HFSExplorer

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.

However, on the plus side, there is no size restriction per file.

Here is how to use HFSExplorer to open DMG files

Step 1: Download and install Java SE Runtime Environment 5.0 or greater version.

7-Zip Free

Most PC users are familiar with 7-Zip utility. If you haven’t used 7-Zip before this, it’s a free tool used to compress and uncompressed files. In addition to 7z, Zip, and RAR formats, 7-Zip also supports DMG format. However, it’s important to note that 7-Zip supports only unpacking of DMG files.

Dmg File Extension

Can I Delete Dmg File After Installation

Easier solution:
Move the DMG to /tmp/ before opening it. Then forget about it.
Files in /tmp/ get deleted on reboot.
If you decide you want to keep it, move it back to your Downloads directory or wherever you want it.

Great Idea!
So the cmd whould be:
mv '/Users/MyShortUsername/Path/To/MyDownloaded.dmg' '/private/tmp/'
Obviously, you must replace 'MyShortUserName' with your correct username , replace 'Path/To/' with the correct path to your dmg file and finally replace 'MyDownloaded.dmg' with the correct name of your dmg file.
If you don't use the quotes for the source path and the destination path, just remember to escape the spaces in the paths with backslash! (')

You know, you don't have to use /private/tmp. Just /tmp will do. In fact, it's preferred to use /tmp.

I go the other way. I keep ALL dmg files.
Every so often I move them to an 'Installers' folder, thus keeping the downloads folder clear. Less often I check the total size of the Installers folder and back up to CD/DVD and then clear it.

Or you could use a crontab:

With something like the following:

This will move any files in the ~/Downloads/ folder, to a child folder called 'archive' on a daily basis... then after 30 days, delete it.

Although, run at your own risk... its job is to actually delete data.

Wait wait, let me get this straight… if I have files I don't want to keep, I can put them in the trash to get rid of them?
God bless Mac OS X Hints.

Good luck USING them after you put them in the trash. This hint was about continuing to use DMGs that are in the trash. You know you aren't going to want to use it, so always throw it in the trash, then continue using it.
Personally, I download to the Desktop so everything I download is extremely obvious to me. I also have it sorted by 'Last Modified' so DMG downloads appear in the upper right. Can't forget those!
