Opening dmg. How to open a DMG file

If you decide to change the Windows operating system to Mac OS and even downloaded a disk image, then you will encounter one problem. The fact is that the Mac OS image is made in dmg format, which is not supported by other operating systems. To record a dmg file, you will need to convert it to iso format or use special software.

You will need

• - UltraISO;
• - TransMac.

Instructions

Search the Internet and download the UltraISO program. For example, you can use the link to the official source http://ultraiso.info/download. This application is designed for creating, editing and converting various formats, including converting dmg files to iso.

Install and run the UltraISO program. Open the "File" menu and click on the "Open" link. Specify the path to the dmg file that needs to be converted to iso format. Click on the “File Type” drop-down menu and check Mac (*.dmg, *.timg, *.hfs) so that the files with the desired . Confirm opening the image.

Right-click on the downloaded dmg file and click the “Extract to” button. Specify the path to save the file in iso format. After this, you can freely burn a disk image using standard operating system programs or other applications.

You will use the TransMac program, which is designed to directly work with dmg files under the Windows operating system. You can download the application at http://www.asy.com/sharetm.htm or another alternative source. The program is paid, but has a 15-day trial. This is quite enough to write a dmg file once, so you shouldn’t immediately spend money on activating it.

Sooner or later, any user encounters a dmg extension file and wonders: how and with what to open it?

But to do this, you must first understand what the “dmg” format is?

For those who first encountered a file of this format, it is unclear what kind of file it is and how to use it. But those who often use virtual disk images see them regularly.

Initially, the dmg format was used exclusively on the Mac OS operating system from Apple.

This extension was created to optimize the work with archives of Macintosh users. This is usually how you save a boot disk to reinstall Mac OS.

In this case, it will not be possible to open the file using standard means, so you will have to resort to the help of special programs, most of which are provided free of charge and in the public domain.

You can unpack the file, or you can convert it into a format available for these platforms.

On the Mac OS operating system, opening such a file is not a problem, since a program called Apple Disk Utility is preinstalled specifically for it.

It is impossible to open such a file in Windows, but there are a number of third-party applications created to unpack it.

However, you can not only open it in the downloaded application, but also convert it into the .

In any case, it is worth paying attention to this article, as it reveals the secrets of unpacking files of this type.

How to open a DMG file on Mac OS

The dmg file format is originally a format of this operating system. Therefore, in this case, third-party programs are not required to open the file.

The unpacking process is quite simple:

1 Double-click the left mouse button to open the file. A preinstalled program will automatically launch and mount the image.

2 Launch Finder, look for the mounted virtual disk in the left column and go into it.

3 After this, you can run the program on your computer.

Thus, we see that on Mac OS it is much easier to open a file of this extension than on Windows thanks to the pre-installed utility.

However, there are special programs that can convert this extension into one available for Windows. Or you can open the file without converting it, but simply download third-party software.

The utility is in first place in the top programs that can open a file with the dmg extension.

It allows the user to see the contents of the file before unpacking begins, which is a big plus. It is not unique in appearance, but in functionality it is slightly superior to similar ones.

The most convenient and popular program to open files of this type on Windows.

In appearance, the program resembles a standard archiver utility. But there is a distinctive feature - the “Extract” button, which means “Extract”.

After clicking this button, files are copied from the image to the computer’s memory, which can later be modified or used as you wish.

The application menu is quite simple, consisting of four commands: open, extract, settings and help. The program is shareware, you can download it on the official website of the developer.

In the Free version, the maximum size of the unzipped file cannot exceed 4 GB, but when you purchase a license, the limitation will be removed automatically.

• “Great program. Easily unpacks dmg files."
• “Good interface, quite clear and simple program. I recommend it to everyone!”

An alternative to the previous option for opening DMG extension files. The program is completely free and available for download in the public domain.

It provides the ability to view system files used by Mac OS. This utility can open files of any size without restrictions.

The downside of this application is that it cannot convert or emulate .

To use the program, you need to install additional software, namely Java Runtime.

After installing HFSExplore, shortcuts to dmg format files will change their appearance and will open when double-clicked.

The program has a Russian-language interface that does not distract the user's attention while working.

Simple controls will help even a beginner to cope. There is a user manual that you can open at any time if anything is unclear. But most likely you won't need it.

User reviews about the program:

• "Very grateful! The program is simply super!”
• “An excellent program, I always use only it, it never lets me down!”
• “A proven option, albeit a demanding one.”
• "The best of its kind!"

Works with many formats, and dmg is no exception.

You can download the program on the developer’s official website or on a third-party resource, but it is free only in the trial version. The limitation is only in functionality. You can unpack files no larger than 300 MB in size.

But there is also an advantage in this program - conversion from the DMG extension to ISO.

You can open the dmg file as follows:

1 Open the program and select “File” in the top menu. In it, click the “Open” button.

2 In the explorer that opens, select the path to the desired file.

3 We wait until the opening process is completed.

4 By right-clicking, open the menu and select “Extract to”.

5 Select a location to save the file.

Thus, we unpack the file in a short period of time. Among the majority of users, this program has been a huge success for several years.

In reviews, people admire the simplicity of the interface and functionality of the program, as well as the capabilities and constant “weight” of the program.

Among other similar programs, UltraISO has a rating slightly lower than.

User reviews:

• “The program is just super, I recommend it to everyone”;
• “For opening dmg files, it’s the easiest. No hassles, easy to use. You can open almost any extension, which is undoubtedly encouraging”;
• “I think the biggest advantage is that it’s free. So many years of consistent quality of the program is simply amazing! Respect to the developers and further success."

7-Zip

This program is the easiest way to extract a DMG file. The utility is so versatile that it unpacks a great variety of extensions.

Allows you not only to unzip the file, but also supports reading it directly in the program. You can work with the contents without unpacking the file.

This way you can edit, copy, delete and change the content. You can download and install the application for free from the official website.

Let's look at the instructions for using this program:

1 Find the required file in Explorer.

2 Right-click and select “Open with...”.

3 In the proposed options, find and click on “7-Zip”.

4 The program immediately opens the contents of the file, which you can work with freely, and all changes will take effect upon completion of work.

Windows users who decide to try the recently popular computer technology from Apple inevitably have to deal with things that are unusual for them. One of these things is the installation of additional programs, which at first glance seems quite unusual. After all, MacOS X does not have the usual .exe files that launched the installation of software in Windows. Instead, “obscure” .dmg files are most often provided

In fact, there is nothing unusual about installing programs on Apple computers, except for one nuance, which we will discuss later. .dmg files are images of a disk or folder in MacOS X operating systems. Their equivalent in Windows are images with the .iso extension.

How to open a .dmg file on MacOS
In their “native” environment, .dmg files open very easily.

1. Having received a file with the extension .dmg from the Internet or another source, double-click on it with the left mouse button, or perform a similar action on the touchpad. This action will launch Disk Utility, which will mount the image on your computer.
   
2. Launch Finder and look for the newly mounted drive in the left column of the list of devices. Enter it.
   
3. If there is no readme file inside the disk that describes further steps, then simply drag the file contained on the disk into the programs folder. After this, you can run the program on your computer.
   

How to open a .dmg file in Windows
Despite the fact that .dmg files are not intended for Windows, you can nevertheless open them in it using one of the following methods.

1. Open the .dmg image using the 7-Zip archiver. This free archiver, among other things, can view and extract the contents of dmg images. True, this is where his abilities in this area end. He will not be able to mount the disk from the image or add anything to it.
   
2. Convert DMG to ISO. This can be done directly in the Windows terminal with the command:
   

   hdiutil convert image-path.dmg -format UDTO -o image-path.iso

   
   
3. If you don’t like the prospect of working with the command line, then you can use special utilities for converting DMG to ISO, for example UltraISO, Magic ISO Maker, or a utility for extracting the contents of the .dmg file DMG Extractor.
   

Content

Some files, for example, game files or data folders, take up a lot of space on the hard drive and need to be compressed to write them to disk. Different systems and utilities have an individual extension of the saved data, for example, the dmg image corresponds to the Mac OS operating environment. Specific files can only be opened using special software.

DMG file - what is it?

For 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? This is data that was recorded on an Apple computer with their operating system. This extension was developed to achieve maximum optimization when working with archives for all Macintosh owners. As a rule, this is how you save your Mac OS boot disk when you need to reinstall it.

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, it is necessary to unpack files in another working environment, for example, Android or Windows. This cannot be done 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 among Windows users because it cannot be opened by standard applications or through the command line. There are many different programs for extracting documents that perform the same function, but differ in interface and number of additional functions.

3. Settings.
4. Help.

DMG is an extension of the disk image in the MacOS operating system (analogous to ISO for Windows). It is used to read the virtual disk data and launch the program installer. DMG is supported in all OS versions, starting with MacOS X.

Format features

The format appeared as a replacement for IMG images, which allows data compression with a minimum number of errors. The resulting files take up less space on your hard drive, and there is no need to download third-party programs to create them. It is enough to use a standard explorer, with which you can generate a DMG or view its contents.

How to open dmg extension?

To open the dmg format on a Mac operating system, simply select the file in Explorer to start the installation. To view compression properties and edit DMG content, you must use one of the following programs:

• Apple Disk Utility is a standard MacOS application for working with disk emulators;
• Incredible Bee Archiver - a packer and unpacker for DMG, with which you can extract the contents of a file to move it to other file systems;
• Catacombae HFSExplorer is a simple explorer for all disk image formats that are supported on MacOS. The program finds all virtual media files stored on the PC and displays them in the main window.

To view DMG on Windows, use the following software:

• 7Zip - the archiver only allows you to view the contents of the disk, without the ability to convert, execute or edit it;
• PeaZip - opens the contents of the image and allows you to add new files to it;
• Acute Systems TransMac - converts files with MacOS code for Windows.
