I know. Recently I dig through MSDN and found this way to determine real filename without
using os.listdir (it's too expensive in Python). You need pywin32 library for this, or
writing C-extension. Using ctypes is also possible but it's too verbose in Python.

Here the actual code:

import win32file
names_list = win32file.FindFilesW(path_in_question) # returns list of WIN32_FIND_DATA structs
# if path_in_question contains wildcard characters * or ? then we get list of al matching files,
# like with glob function
real_name = names_list[0][8]

Here is example running in bzr.dev tree:

In [4]: import win32file

In [5]: names_list = win32file.FindFilesW('BzR')

In [6]: names_list[0][8]
Out[6]: u'bzr'

In [7]: len(names_list)
Out[7]: 1
