Well 2 days ago I got this error (below) when trying to move a file. I then tried to move/delete/copy/rename some other files (on the desktop, Documents, etc) and some files have no problem and some get this "Invalid MS-DOS Function" error.
Comment if you know anything about this.
I have tried running disk check
I have tried running CHKDSK command from command prompt (with Amin rights)
I have tried just restarting the PC.
I have tried running "dism /online /cleanup-image /restorehealth", Dont know if it worked, but will be restarting pc to see.
