I have on a network drive a folder that contains downloaded movies and TV shows. If I try to open the folder so I can play a file, I get the "handle is invalid" message. I had this problem with Windows 7 and the problem has stayed with the upgrade to Windows 10. If I go to a different PC that is connected to the same network but is running Ubunta, I have no problem playing any of the files (movies). I have copied/pasted the folder to another drive but the Windows problem remains. Help.
