You are correct on this. AFIO supports kernel side globbing during 
directory enumeration on Windows, with a user side emulation on POSIX 
(basically fnmatch()). In fact, kernel side globbing is so quick it 
is how AFIO stat's a single file entry, it simply sets the glob to an 
exact match and that's three orders of magnitude faster than the 
traditional way of opening a handle, reading metadata and closing the 
handle.

I was not aware however that the NT kernel glob is any different to 
Unix glob. It is of course totally possible that the NT kernel glob 
is totally separate to the Windows glob which no doubt is DOS legacy 
encumbered.
