A list of 9 eula. and 11 install.res related files, a globdata file and three VC-RED files have appeared in my E drive as 'Files at drive root'

My main drive is my C drive, and during upgrading I disconnected the E drive.

They are not large files but I can't help spotting them when they are right under files I do recognise. I seem to recall someone somewhere saying it's best just to leave them but mark them as hidden so I can't see them. Am I remembering correctly?
