| Description | The DMG file extension was created by Apple and is primarily used on Macintosh computers and devices. In most cases, the DMG file is used to give the Mac devices the ability to install different types of files and software originating from the internet. The DMG file is essentially a mountable disc image that shows up on your desktop when opened. The file contains raw data that is usually both encrypted and compressed. Mac systems treat DMG in the same way they would treat an inserted disc, and they instantly try to open or 'run' the file. | ZIP is an archive file format that supports lossless data compression. A .zip file may contain one or more files or directories that may have been compressed. The .zip file format permits many compression algorithms, though DEFLATE is the most common. |
| Technical details | The DMG file extension was specifically designed for Macintosh computers, and users are likely to have a lot of trouble if trying to use them on a Windows device. There may be instances where one can convert the files, but it probably needed to look for additional utilities to allow the file to be accessed from the chosen device. There are also executable files that can help with this. However, if the original DMG file was password protected by Apple, those executable applications may not work. The DMG file has several different formats, including Linux, Fat32, UFS, ProDOS, HFS, and HFS+. | ZIP files are archives that store multiple files.ZIP allows contained files to be compressed using many different methods and simply storing a file without compressing it. Instead, each file is stored separately, allowing different files in the same archive to be compressed using different methods. |

If you own a Mac, you’ll eventually need to transfer files and folders to others. To do that, you’re going to want to shrink - or compress - the files so they take up the least amount of space possible. That way, it will be easy to move your files via email, FTP, or even with an instant messaging application.
In the past, Mac users had to rely on an expensive application called Stuffit to compress files and folders. That application’s still around, but it’s no longer necessary the way it once was. In fact, macOS has built-in features that allow you to compress - or zip - files and folders on the spot. You can also uncompress zipped files and folders - it’s all built into macOS.
Here’s how to compress files and folders on your Mac:
Locate the file or folder you want to compress. You can select multiple files and folders by holding down the Shift key (for multiple items) or the Command key (for several individual items) and clicking.
After you’ve selected the files and folders, right click on them, and then select Compress.
A window may appear indicating that your Mac is compressing the files or folders. Depending on the size of the files or the folders, this could take a couple minutes.
Once your Mac has finished compressing the files or folders, you’ll see a nice little zip file. This contains all of the files and folders you selected to be compressed. Just send this to your Mac- or PC-using friends - they’ll be able to open it. All Mac users have to do to open the zip file is double-click it!

How Small Can You Make the Files?

How much space can you save by compressing? That depends on the type of files you’re trying to compress. Generally speaking, a zip file will be about 10% smaller than all of the files were before they were compressed. This feature works best with medium size files - compressing lots of small files or one or two big files won’t save you much space.
