[Egor Bolonev]

hi all

i want my program to ignore ntfs links, but os.path.islink() isnt work as
i expect

print os.path.islink('''C:\Documents and Settings\åÇÏÒ\My
Documents\Scripts\Antiloop\'''')
outputs
False

far file manager said 'C:\Documents and Settings\åÇÏÒ\My
Documents\Scripts\Antiloop\' is link

how to detect ntfs links?

=program======
import os, os.path

def get_all_files(path):
if len(path) > 0:
if path[-1] == ':':
path=path+'\\'
try:
for i in os.listdir(path):
j = os.path.join(path, i)
if os.path.isdir(j) and not os.path.islink(j):
for ii in get_all_files(j):
yield ii
else:
yield j
exceptass

for i in get_all_files('c:'):
print i

There are no ntfs links. What appears as a link on GUI level is
nothing but a plain file with special content, so that
os.path.islink() tells the truth. Windows "links" are a special
Windows feature (shortcuts) and must be detected via Win32 api
calls or by searching for content characteristics of shortcuts.

What he's telling you is that Windows doesn't implement symbolic links.
os.path.islink does not detect what you think it does.

You may well be able to do it with the win32file module
functions: GetFileAttributesEx or GetFileInformationByHandle
It's not my area of expertise, but usually a bit of poking around
in msdn.microsoft.com yields some results, as does Googling
around for other people (often VB or Delphi-based) who have
done the same thing.

You're wrong, NTFS supports symlinks for directories and hard links for
files:

Thanks for the update and my apologies to Egor. I was using Win2k for
two years and never saw a link, neither at system nor at application
locations. How nasty of Microsoft to add this feature so silently

IIRC this is something they had to add for the US government (probably
something to do with posix compliancy?), but that they don't want people
to use... ;-)
