When you try to delete the mountUUP folder from your Windows 10 or Windows 11 computer, an error message may sometimes pop up informing you that you need permission to make changes to the respective folder. Or you may get an alert that says the file is already in use.
The most annoying thing is that the mountUUP folder sometimes takes up 8-15GB of storage space on your drive. Removing it helps you free up precious space on your device. Let’s see how you can delete the stubborn mountUUP folder without further ado.
How to Delete the MountUUP Folder on Windows PCs
Dismount Existing Windows Images
To fix the issue where you can’t delete the mountUUP folder on Windows 10 or Windows 11, you need to dismount existing images.
- Launch Command Prompt or PowerShell with admin rights.
- Run the dism /get-mountedwiminfo command to locate existing images.
- After locating the images, you need to dismount them. To do that, enter the following command:
dism /unmount-image /mountdir:”c:\mountuup” /discard
- If this command doesn’t work, try running DISM.exe /Unmount-WIM /mountdir=C:\MountUUP /discard
- Then, navigate to c:\mountuup. The folder should be empty now, which means you can safely delete it.
By the way, if your image is not stored on the C: drive, replace “c:/mountuup” with the full path to the mountUUP folder as available on your machine.
