File extension .DMG

File description

The DMG extensions are treated as the actual hard drives when run by the Macintosh OS X systems. They can be easily created using a Disk Copy, that is burned into a CD form or can be mounted as an usual volume on Macintosh systems. They normally comprise of raw blocks of data that are compressed for easier file management.

The DMG file extensions are not meant to be utilized on the Windows operating systems. On the other hand, the Daemon Tools are generally utilized for mounting virtual drives by using the .DMG extensions. There are some other applications too, that can be used to convert the DMG file formats in other recognizable format that work for Windows operating system as well.

Description of the problem

If you have on your computer a .DMG file that you cannot open, you are in exactly the same situation as thousands of other people who have similar problems with this or any other unknown file.

There may be several reasons why you cannot open the file with .DMG extension. Directly on this website you can find a solution of the most common problem with the .DMG file – that you do not have on your computer the appropriate program to open the file.

Solution

From the list below, select the appropriate program, install it and double click on the icon of a file that did not want to open - the problem with the .DMG file extension should be solved. However, if this does not happen, go back to the website to learn about other possible causes of the error, which have been described at the bottom of the website.

Other possible reasons why your .DMG file does not want to open

In addition to the problem described above, i.e. the lack of the appropriate application to support the .DMG file, there may be several reasons that cause problems with opening and operation of the data format:

1. Incorrect version of the installed application

A quite common problem is the lack of application in the appropriate version. Even if you have an application, with the help of which you should open the .DMG file, you may have a problem with it because of its version. Perhaps in previous versions the application has not yet supported the .DMG file, so download the update and check again.

2. Incorrect .DMG file association with the program

If you have already installed the appropriate application, and it is the correct version, the file may not open correctly, because the operating system does not have information that this program supports the file. So you need to "show" which program the computer should use. To do this:

Right-click the .DMG file
Go to the "Open with" - then "Choose default program ..."
Locate the appropriate application
Click "OK"

3. The file is corrupt

It also happens that the file you want to open is corrupt and therefore there is no such possibility. In this situation, you should find its different version, or ask a person from whom you got, to send it again.
