It could very well be a bug in Windows, too.  I think I ran across one 
last night.

Sometimes win32's os.stat(...) raises an exception for folders that 
*do* exist.  The only case I ran into was an iPod though.  The iPod is 
a 3rd generation 15gb (read: not a new click wheel), FAT32 formatted 
(fresh restore from the win32 iPod Updater) managed by iTunes with 
"Enable disk use" on, and is plugged into a laptop with a "low speed" 
USB port (I think 1.1, whatever was before 2.0).  It is mounted as 
'F:\\' and it has several folders on the root (IIRC ['Notes', 
'Calendars', 'Contacts', 'iPod_Control']).  Nothing special about any 
of the folders, except iPod_Control which is attrib +h.

os.stat fails on EVERY folder except 'F:\\iPod_Control'.  
os.listdir('F:\\') shows them all.  win32api.GetFileAttributes works on 
all of these folders and returns just FILE_DIRECTORY (or whatever it's 
called, I don't have a win32 machine where I'm at right now; the 
constant is 16).  iPod_Control probably returns a slightly different 
set of flags, I don't remember trying it.

os.stat('F:\\Notes\\Instructions') succeeds (Instructions is a file).

I believe this may be a bug in _wstat64i (name may be slightly wrong.. 
from memory) or something?  I tried it on Windows XP (not SP2, but 
should be otherwise patched up) with the python.org distributions of 
Python 2.3.0 and Python 2.3.4 and got the same results both times.
