Do you want to move the file out of the folder?
Do you want to move the file out of the folder while in process?
Just Drag and drop.
For editing with NTLite after moving the file, use the option add image file.
I don't know if that is what do you want or if you want to move and then later install it from another path.
Setup can install from a different WIM path, using two different methods.@kalede888, if you mean can you install Windows with install.wim being elsewhere in the ISO, then no as far as I know.
But there is a way without Windows setup. Boot WinPE (boot.wim) and use DISM to "Apply" the image to the partition.
Search online how to use DISM to Apply WIM, if that answers your question.
