Hi !
I wrote to Python list, but nobody answer to my problem.
I copy these mails to this body.
So: I need to optimize my disk hasher code. I need to make quick code,
and I see that FSUM make better speed than python sha/md5 with py2exe.
But I need to "transport" filenames to FSUM.
I got errors with unicode file names. See my unicode test file name:
UFN=u'%s\\xA\xff'%os.getcwd()
I want to get an universal code the convert (unicode) long path to short
path.
Here are my tryings:
Hi !
Ahhh... That is not working in my notebook...
See the log of the program:

NOT FOUND ***** xAy

It is interesting. In my working machine the code of my shortpath
routine generating xAy result as short filename.
In my notebook (as you see) it is generate XA02BB~1 file name.
This filename not found by FSUM.exe.
If I open it as:
f=open(shortfilepath,'r')
print f.read()
it is working from Python, show the file content good.
Hmmmm..... Is Windows doesn't have compatible way of file reading ???
(In this notebook I see any interesting things too. Some file copied
from CD - I got invalid times for them. When I copy them to my
working machine, everything is ok.
Windows not compatible itself... :-(((
Both of machines have WXP, same updates in them, and NTFS used. What
is different ? I don't know)

Hi !
I trying with that, but I get error, because the result is unicode
too... :-(((
from ctypes import windll, create_unicode_buffer, sizeof, WinError
buf=create_unicode_buffer(512)
if windll.kernel32.GetShortPathNameW(UFN,buf,sizeof(buf)):
name=buf.value
print [name]

Can I do anything with this unicoded filename ? My code must be
universal !
Thanx for help:
