How to Mount and Unmount ISO Files in Windows 11
You mount and unmount ISO files in Windows 11 using its built-in File Explorer. An ISO file is essentially an archive that perfectly replicates the contents of an optical disc, such as a CD or DVD.
When you mount an ISO, Windows 11 creates a virtual disc drive, allowing you to access its contents as if you’d inserted a physical disc. This is incredibly useful for installing software or games that come in ISO format, like many older PC titles from the early 2000s.
You won’t need any extra software because Windows 11 handles this process natively, making it super simple for you to use.
Mount an ISO by opening File Explorer, selecting the ISO, and clicking Mount in the ribbon or context menu. Unmount it by right-clicking the virtual drive under This PC and selecting Eject.
What happens when you mount an ISO?
Mounting an ISO file in Windows 11 makes it appear as a new drive in File Explorer, just like a CD or DVD.
