It looks like Windows CE takes (only?) level 260 but I can't easily
prove it without access
to a test system (I just have some customer traces) - so how does
(Windows XP/Vista/7 etc.) determine which FindFirst level to send to these
given that the Microsoft server in this case is reporting NT Find and
NT SMB support but in
practice not supporting most FindFirst levels.
