An ISO file or image is a compilation of data that contains all necessary files and applications to run a program. ISO images substitute physical disks, such as CDs and DVDs, that would instead have been needed to install a program. It is commonly used for large software such as operating systems or games.
Like a physical disk, an ISO image needs to be mounted first before being run. Mounting means accessing the ISO file’s contents similar to how your computer would read a physical disk. You can think of it as your computer simulating a CD running, but instead, it is software that it is reading.
You have two ways to mount an ISO file. The first method is using Windows’ own ISO mounting program, and the second would be using third-party programs. The first method is only available if you are using Windows 8.1 and above.
How to Mount an ISO File in Windows 8.1 and Above
1) To mount an ISO image with its built-in mounting program, first, navigate to your ISO file’s location.
2) Second, right-click the ISO file to open its context menu. In this menu, you can see various actions that you can do with your ISO, such as open, delete, copy, cut, open with, and more.
3) Select Mount from the context menu. Depending on your computer’s processing power, it may load for a few seconds before the mounting is complete.
4) Go to My Computer (if below Windows 10) or This PC (Windows 10 and above).
5) Under Devices and drives, click on the DVD Drive with the name of your ISO file. This will open the ISO file to show you its contents.
