Detected file in use


New Member
After updating to the most recent version of NTLite ( I keep getting the following error every time I try to build an image:

Detected file in use within the mount directory. Please retry when the resources have been freed, or cancel and reboot the machine.

As far as I'm aware, nothing else is open that would be using the mount directory. I also then cannot unload the image and have to delete the reference in the registry.

Any ideas what could be causing this?

I have no idea how you encountered it. On my side it happends when I have opened explorer in mounted folder, or file in Notepad etc.

Does problem persist after rebooting too?

Can you unmount all wim using this command?
dism /cleanup-wim
i have had the same issue. After test and trial, i found out that my antivirus was stopping me from editing or mounting the app.

Please disable if there is any ransomware gurard or antivirus. And test it then
