Some files, for example, game or data folders take up a lot of space on the hard drive and you need to compress them to write to disk. Different systems and utilities have an individual extension of stored data, for example, the dmg image corresponds to the Mac OS operating environment. Specific files are opened only using special software.
Dmg file - what is it
Those who see the dmg extension for the first time, it is not immediately clear what it is and how to use this file. Anyone who works with disk images can encounter it. What is a DMG file - is the data that was recorded on a computer from Apple with their operating system. This extension was developed in order to achieve maximum optimization when working with archives for all Macintosh owners. As a rule, this is how the Mac OS boot disk is saved when reinstallation is necessary.
On all Apple computers, this format does not cause problems, because there is a built-in program for working with images - Apple Disk Utility. In some cases, you need to unzip the files in another working environment, for example, Android or Windows. This will not work with standard tools, so you will have to resort to the help of special utilities. Most of them are free and very easy to learn. You can extract data or convert the image to another format.
How to open DMG format on Windows
Most problems with this extension occur for users of Windows, because it cannot be opened with standard applications or through the command line. To extract documents, there are many different programs that perform the same function, but differ in interface, the number of additional functions. You can change the contents of the image, but they will be saved already on your hard drive, and the previous version will be inside the archive. If you met the DMG format, than opening in Windows will be described below.
One of the most convenient, popular programs for opening this format. Outwardly, the interface is very similar to standard archiver utilities. The main difference from them is the presence of a button called "Extract", which means "Extract." When you click on it, documents are copied from the image to the computer, which can be used or modified. The current version can always be downloaded on the website of the creators of the utility.

On the site you can find a link to download the free version of this application. All functions will be available, but the maximum amount of image that you can work with cannot exceed 4 GB. This is the only negative in the Free version. If you have an archive larger than this volume, then you will not be able to work with it. This restriction will be removed immediately after the purchase of a license.
This is another option than you can open DMG. The utility is completely free, it provides the ability to view images with the HFS + file system that Mac OS X uses. Images of any size (without restrictions) can be opened with this software without any problems. The only negative of this option is that you cannot emulate or convert data to a virtual disk. To use the utility, you need to install Java Runtime. After installing HFSExplore, all DMG files will change the appearance of the shortcut and will automatically open when you double-click.
