The GetFullPathName API is limited to 260 characters, unless one uses the Unicode version and uses the \\?\ prefix, which extends that to 32,768. I'll have to check the library source code to see which one they use. > (2) The fact that abspath(path) swallows the windows error, returning > something that is definitely wrong (a relative path where an absolute > one is expected) makes it hard to use it safely.

The relpath operation is tricky, because it's possible for paths to have things like a\b\..\..\c\d\..\other. You generally want to unravel all of that before you begin. -- Tim Roberts, t...@probo.com Providenza & Boekelheide, Inc. _______________________________________________ python-win32 mailing list python-win32@python.org http://mail.python.org/mailman/listinfo/python-win32
