Question: fopen does not work

The command

fd:=fopen("C:/temp/",'WRITE');

suddenly does not work. I keep getting a 'permission denied' error message. I haven't had to write anything to a file for a while so do you think the recent windows update screwed something up? In fact, I can't seem to write any file anywhere. It was working weeks ago. My apology if this ends up being a lame question. :)
