[Fix] Can’t delete NLTmpMnt from the Temp folder

When you use Disk Cleanup or manually attempt to clear the %temp% folder of your user profile, the “NLTmpMnt” subfolder in your Temp folder can’t be deleted. You get the following error when deleting the folder:

Folder Access Denied

You need permission to perform this action.

You require permission from [username] to make changes to this folder.

Also, deleting the folder via Safe mode or using tools like Unlocker may not help.

Cause

The above error occurs because “NLTmpMnt” is a mounted folder. You may have used NTLite (www.ntlite.com) earlier to mount an image but did not unload (or unmount) the image.

Resolution

The correct way to delete the “NLTmpMnt” folder is to unmount it. Please use one of the methods below to delete the folder:

Method 1: Using DISM

Please open an admin Command Prompt and run this command:

Dism /Unmount-image /MountDir:"%Temp%\NLTmpMnt" /discard

Press Enter.

Method 2: Using NTLite

Launch NTLite and see if there are any mounted images.

Right-click on the mounted image under the “Mounted” section and click Unload. Click OK.

Do this for each mounted image listed on that screen.

Note: NTLite records the results of the last mount/unmount operation in the %temp%\NTLite.log file.

That’s it. One of the above two methods should completely delete the “NLTmpMnt” folder.
