The dmg extension is most often encountered by users of the Mac OS operating system. A dmg file is a classic disk image. The file with the current extension can store any data similar to . Additionally needed.
This article will tell you how to open a dmg file on Windows 10. The user has the opportunity to simply view the contents of the dmg file using one with . If this option does not suit you, use any program to convert a dmg image to iso. After converting it into an image that is familiar to us, you can mount it or write it to media.
In all unclear situations, to open unknown file formats it is often enough to use one of the popular archivers. If you already have one of these archivers installed, then you don’t even have to look for how to open dmg in Windows 10. The archiver developer’s website immediately indicates supported file formats.
Launch in Windows 10. Next, click the menu item File > Open, and in the Explorer window that opens, specify the location of the file with the dmg extension. Then, if necessary, you can simply drag the contents of the dmg file to the location desired by the user.
If the option of unpacking the disk image does not suit you, then you can use conversion tools. In most programs, the user simply selects the output file and the destination disk image extension. The iso image extension is optimal for users of the Windows 10 operating system.
To convert images, we recommend using the well-known UltraISO utility. It supports all current disk image formats. In principle, using UltraISO you can both view the contents of a dmg file and convert it into an image of a format familiar to users.
Run UltraISO as administrator. Go to section Tools > Convert. In the window that opens, specify the file to be converted, the directory where the source file will be saved, and the actual format in which the disk image will be saved. After pressing the button Conversion wait until the file format change process completes. 
If necessary, users have the opportunity to use many other programs that allow them to convert a dmg file to iso. Some of them weigh only a few megabytes and will not constantly require you to purchase the full version of the program.
- AnyToISO is a free converter of disk images of various formats to iso. Both compressed and encrypted disk images are supported, and conversion occurs without data loss.
- Magic ISO Maker is a very old program with the ability to convert dmg images. Despite the program not being updated for many years, it still works on modern operating systems.
Conclusion
Nowadays, it is extremely rare to find disk images in the dmg format, especially in the Windows 10 operating system. But the ability to open or convert a file with the dmg extension is present. If necessary, using one of the above programs, you can simply unpack the data from the image to the user’s local disk.
No version of the Windows operating system supports the DMG file format. Therefore, for those who have already downloaded files with the .dmg extension and want to open them, you will also need to install one of the programs on your computer or laptop, which will be discussed in this article.
Let's look at three free tools for opening DMG in Windows 7 and 8.
DMG Extractor
DMG Extractor is probably the first and only tool designed exclusively for opening DMG files on Windows. Using this particular program allows you to avoid converting .dmg files to other formats.The only catch with the free version of DMG Extractor is that it can only open DMG files that are no larger than 4GB, but this shouldn't be a problem for most users.
DMG Extractor is very easy to use. First, download (the file is located a little lower in this article) and install it on your computer. After that, right-click on the DMG file and select “ To open with» → « DMG Extractor».
Download DMG Extractor for free
HFSExplorer
The second free program for opening DMG files. It is less popular because it also requires installation of Java SE Runtime Environment 5.0 or higher version before operation. And this is already an extra waste of time.Also, notably, HFSExplorer does not support all types of the DMG format. Which ones specifically, unfortunately, I cannot clarify. But this program also has its own advantage - it has no restrictions on the amount of memory of disk image formats, unlike DMG Extractor.
Hello friends, today I will write a few words about the dmg format. Many users have encountered it more than once. The problem is that not everyone knows how to open a dmg file. This extension can hide anything, for example, movies, games or music. After downloading one of these files, the user may find the extension dmg. In fact, opening such a file is quite easy, I will show several ways how this can be done.
Before we start looking at the methods, I want to say what the dmg extension is. It's very simple - it's a disk image. You can imagine that the information was recorded on some kind of CD, but the image is virtual. So, how do you open a file with the dmg extension?
If you had Mac OS, you could double-click to open these types of files. In most cases, users have Windows. In this operating system we can use various archivers, such as 7-Zip or other free utilities. There is also a way to convert DMG to ISO format, which opens without problems in modern operating systems.
Using the 7-Zip archiver
This archiver has quite broad capabilities. Opening files with different extensions is almost effortless. It's the same with the DMG format. The process of use is very simple. We go into the program, press the button "File", and then "Open" and look for the location of our file. We can extract the files without any problems.
If you don’t yet have this archiver on your computer, you can download it from this link and install it. When downloading, you can choose between 32-bit and 64-bit versions. I have Windows 10 64-bit, so I will download the x64 archiver.
If you want to change something in the image file, you won't be able to do it without extracting it.
Using free utilities
There are many special programs for opening DMG files, but do you know what’s most interesting? They work exactly the same as 7-Zip. The disadvantages in terms of editing files in the image are the same, that is, you cannot change the file without extracting it from the image.
So, one of the popular programs is DMG Extractor. Its interface is simple and similar to that of an archiver. There is a button "Extract", which allows you to extract files from the image.
We can find the file image if we click on the button "Open". In the button "Extract" there are three points:
- Extract files to last location
- Extract all files to... (you choose where to extract)
- Extract selected files to... (select several files and extract to the desired location)
As you can see, everything is quite simple. You can download this utility from here. The site is official, so there is nothing to be afraid of. There are two versions of the program - paid and free. The downside of the free one is that it does not work with images weighing more than 4 GB.
Finally, I will say that there is also a program called HFSExplorer. This is if you didn’t like the previous utility.
Convert DMG file to ISO image
Now we have reached the last option for opening dmg files. We can convert dmg to the ISO format we know. This can be done using the AnyToISO utility or Magic ISO Maker.
There is also a useful utility called UltraISO, although it is paid, but there is also a trial period, which will be enough for you to complete the conversion.
Today, dmg is one of the most popular formats for saving various content and is actively used on Mac OS X, as it allows you to save large files (for example, movies) without losing quality. On the Windows platform, this type is also present, but is not as popular as iso due to the fact that the user will not be able to directly open the file due to standard operating system restrictions. But, with the help of special utilities, you can reformat the dmg format into a standard one, and how to do this will be discussed in today’s article.
What is this format and where is it used?
Dmg is a familiar disk image that is widely used on Mac OS X due to its ability to compress a large file without losing its quality. But, most standard Windows software and third-party utilities do not support this type, which is why you have to resort to third-party methods for converting this postscript. As a rule, ISO is used for this, since these 2 formats are very similar in their functions.
By the way, on a Mac, iso can also only be opened using third-party programs.
How to open a file
There are several ways to open an extension of this type, and each of them should be considered in detail.
We use 7-zip
If you need to open dmg, then the 7-zip utility will come to the rescue. This is a free archiver based on free type source code, which is why it is capable of converting almost any type of extension. Using this software, you can find out the file size (its weight), the number and names of archived postscripts and other additional information.
Open via Ultra iso
Ultra iso is a specialized tool designed to open as well as convert various formats. The application allows you to edit, extract and transform existing source data without unpacking the archive. Ultra iso works with almost all available images, and will also help tightly integrate postscripts from a third-party operating system simply by converting them. 
Ways to check site traffic
Using Apple Disk Utility
Apple Disk Utility is native Mac OS software for working with built-in disks. On Windows, the application is used to convert Mac OS files. It allows you to convert files of various extensions, as well as change them if necessary.
Using HFSExplorer
HFSExplorer is software that allows Windows OS to work with postscripts and formats created on other operating system platforms. Integration occurs through free source code. The utility allows you to view and edit available files. 
How to convert dmg to iso
Dmg2img is special software that allows you to directly convert postscripts from Mac OS to Windows OS. But the main drawback of the application lies in its functionality. It does not have a graphical interface, so all actions will have to be performed using the management console.

How to open dmg - Complete instructions
From time to time, users come across files in the DMG format, but they do not understand how to open DMG and find out the contents of a particular document.
Moreover, these can be various films, games, music or photographs - when a user downloads one of these, he discovers that the file he downloaded has a DMG extension.
Of course, most users encounter this for the first time and at first do not know what to do with it. On the Internet you can even come across the opinion that a file in the DMG format is a kind of virus that it is better not to mess with. In fact, this is just a myth.
Therefore, it would be useful to consider how to open the DMG and whether it is as difficult as it might seem at first glance.
Before you can figure out how to open these files, you first need to understand what they actually are. Any DMG file is a disk image. This means that information is written as if on a regular CD or DVD, but without the disc itself.
Only it is used not in Windows, but in Mac OS X. Such images in Windows have the ISO extension. Most likely, it has now become clearer to ordinary users what this very DMG format is, but the question of how to open a document in this format remains open.
In Mac OS X, any file with this format can be opened by double-clicking the mouse. But in Windows, which we are all familiar with, everything is somewhat more complicated. Here you can open it in one of the following ways:
- 7-zip archiver;
- One of the free utilities for opening DMG.
You can also convert DMG into the ISO that is familiar and familiar to all of us. Let's look at each of these methods in more detail.

In fact, the 7-zip archiver is an almost universal tool that can recognize and open a variety of extensions, not only for reading, but also for fully working with them - copying, deleting, changing content and other manipulations.
The same goes for DMG. The opening process itself is absolutely standard and consists of clicking “File” in the main window (highlighted in Figure No. 1), and then selecting the “Open” command from the drop-down menu.
Next, the user will see a standard selection dialog in Windows, in which he, in fact, will need to indicate where the very file that needs to be opened is located. The pictures below show how this all happens.
No. 1. Main window of the 7-zip program
No. 2. File location selection dialog
What to do if such an archiver is not installed on your computer? No problem! It can be downloaded and installed within a few minutes.
This is the official website. On this page we will need to select one of two options – for 32-bit or for 64-bit. They are designed for different systems depending on the bit capacity. If you have Windows 7 and higher, select the 64-bit version.
On the download page, click on the “Download” button next to the desired document, after which the download will begin.
No. 3. 7-zip archiver download page
To install the archiver, you just need to run it and follow all the instructions. The disadvantage of this method is that in order to edit a file, you will need to extract it from the image.
This means that you cannot edit something and leave it in the image in a modified form. In principle, the same applies to the following methods.
Return to menu
In fact, to open a file whose format is DMG, there is more than one special program. But the paradox is that they all work exactly the same as the aforementioned 7-zip archiver.
They also cannot be used to change the contents of the image itself. Any file can be edited, but in the image it will remain in its original form. But the user will be able to take all the necessary information.
One of the most popular programs in this category is DMG Extractor.
This program looks quite standard. Moreover, its interface is very similar to the most common archiver. True, there is a button “Extract”, that is, “Extract”, which, in fact, allows you to take the contents of the image and use it at your discretion.
The DMG Extractor interface looks like shown in Figure 4.
No. 4. DMG Extractor interface
As you can see, the buttons are indicated by numbers in the figure. Their meanings are as follows:
- Open file. By clicking on this button, the already familiar dialog appears for selecting the location of the file, the format of which is DMG.
- Extract file. In order to use this function, you just need to click on the file in the image and click on this button. After this, three options will be available:
- all files to the last location;
- all files in ... (assumes that the user will choose their location);
- selected files in...
- Write to the creators.
- Help.
In general, there is nothing complicated here, and, as we see, this terrible format is quite amenable to viewing and editing.
You can download this program completely free of charge directly on the official website - www.dmgextractor.com.
On the main page you can find a large button “Download free edition now”, that is, “Download the free version now”. There is also a paid edition, the disadvantage of the free one is that it will not be able to process images that weigh more than 4 GB.
No. 5. Download button for the free version of DMG Extractor
Another similar program is called HFSExplorer. But for some reason DMG Extractor is more popular among Internet users.

There is also an option to convert from DMG to the ISO format that is more familiar to all of us. The following programs can help with this:
There is also UltraISO, which is familiar to all of us, but, unlike previous programs, it is not free. True, there is a trial period during which you can convert all the images you need. You can see how to use UltraISO to open DMG images in the video below.

Opening a DMG file on different platforms
A DMG file is a disk image created in Mac OS. The analogue in the Windows environment is an image in ISO format. Since this format is used on Apple computers, the question of how to open DMG in Windows or Linux causes serious difficulties for users. However, in practice, the problem is quickly resolved: it is enough to know which programs can read the DMG format in order to open the image on Windows or Linux.
Using the 7-Zip archiver
If the 7-Zip archiver is installed on your computer, then use it to view the contents of the image. The WinRAR program does not provide this option, but the powerful 7-Zip successfully copes with the task.
- Launch 7-Zip. Expand the "File" menu and select "Open".
- Specify the path to the DMG.
You won't be able to mount the disk or add new data to it - you can only view and extract the contents. You can also use other programs: the free PeaZip archiver, the DMG Extractor utility (limited to 4 GB in the free version), AnyToISO Converter (limited to 870 MB in the free version) or Magic ISO Maker.
Viewing via UltraISO
UltraISO is actually a paid program, but it has a fully functional demo period, which should be enough to perform simple actions with the DMG file. The advantage of UltraISO over 7-Zip is the ability to add/remove files from the image.
- Launch UltraISO. Expand the File menu and select Open.
- Specify the path to the DMG.
You can mount the disk, but its contents will not simply appear in the Windows environment. The problem is resolved by conversion, which is done using the UltraISO program.
The duration of the conversion depends on the size of the source file. After completing the procedure, you need to open the resulting ISO image in UltraISO and mount it into a virtual drive.
Opening DMG on Ubuntu
There are a huge number of Linux assemblies, but we will look at how to open DMG on Ubuntu, one of the most popular Linux systems.
Instead of Mounty, you can use other applications for working with images - for example, AcetoneISO. The meaning of the work is the same: you specify the path to the file, and then mount the image, after which you can work with it as with a regular optical disk.
Convert to ISO on Mac OS
To avoid the hassle of finding suitable applications, it is better to convert DMG to ISO on Mac OS in advance. If you have a Mac computer at hand, then this operation requires a few steps:
- Launch a terminal.
- Run the command “hdiutil convert image-path.dmg -format UDTO -o image-path.iso”.
After the operation is completed, you will receive a regular ISO image that can be opened on any computer, no matter what system is installed on it.

How to open a dmg file?
Wandering around the Internet, you will one day be able to download a file with the .DMG extension from there. What kind of interesting file is this and how to open it in the Windows operating system. To be honest, at first I myself didn’t know how to cope with this problem and I also had no idea what kind of extension this was. After googling a little, I still managed to open this kind of file, which is what I want to talk about in this article.
And so, a .DMG file is an image that was created using the Mac OS operating system. This is the operating system that is installed on Apple products. Opening this file in Mac OS is not difficult, but most people have Windows installed.
How and with what to open a dmg file in Windows? And so, first you need to download the UltraISO program, you can’t do without it. The program is paid, so I don’t provide links from my website, but if you want to find it it won’t be difficult. And so, download and install.
We launch the program, click on the “File - Open” tab and look for your file with the .DMG extension.
As you can see, it was loaded into our program without any problems and we can easily view the contents of the archive and open the files you need.
Now you can try to extract all the contents of this image into a separate folder. To do this, click on the “Actions” tab and select “Extract” from the drop-down menu.
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.
- 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.
- Launch Finder and look for the newly mounted drive in the left column of the list of devices. Enter it.
- 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.
- 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.
- 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
- 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.
