[racket] Behavior of file-exists? and directory-list

I don't see any of these things, directory-list returns the same
number of files for me as dir (if I include hidden files) or the
explorer in "windows\system32" on windows 7 and 8. It also picks up if
I add a file of my own there. This is on 64-bit versions of Windows.
