I have a number of files that were in my My Documents folder in my old Win 7 PC. I recently bought a new machine with Win 10 preinstalled. I have copied some of those old files on to a portable drive and want to copy them again to the Documents folder on the new one. When I try I get a message telling me I can't open the file because I don't have permission to do so. I'm logged in as Administrator but that doesn't help. I've tried a number of suggestions from on the web but nothing has worked, and in some cases the options suggested just don't exist. Can someone please help me with this problem, as I need to use some of those files.
