Where are the Windows 10 Media Creation Tool temp files located?


Apparently my 8GB USB drive has some error that disables it from letting the Windows 10 Media Creation Tool (MCT) install the ISO onto it, so I've found another way to do it.


However, the temp files from the MCT download have taken more than 10GB of data somewhere on the drive that I don't know how to locate.


Does anyone know where they are located so that I can manually clean them up?


Answer



It is created on the drive(usually c:) where your current windows folder is, in a hidden folder called c:\$Windows.~WS, before the final Windows.iso was created in a folder of your choosing.


You can unhide files in view, folder options, view, in file explorer.


It does not get deleted after the Iso is made and contains about 6GB of files because it contains both sources\Installx86.esd and a nested sources\Windows\sources\Install.wim windows images.


The Windows folder containing the install.wim seems to be identical with the contents of the final windows.iso.


If $windows.~WS is like $windows.~BT, you cannot delete it by normal means, but try first anyway.


If not, you can probably delete it by doing a disk cleanup. Right click the drive, select properties from the bottom of the list. In the general tab select disk cleanup, wait for it to calculate, then click clean up system files, wait again then while it finds all the update files - hopefully it will remove the folder then, and select OK to delete it.
