[python-win32] opening files with names in non-english characters.

[Gerdus van Zyl]

I see a couple of problems with your code:

1. where is n first given a value and what is it total file count,
etc? also you decrement the value, do you want the last file in the
directory or something?
2. The if os.path.isdir(full_path): .. findFile(full_path) part
doesn't return or handle the value so it's not useful so far i can
see. So you either need to "return findFile(full_path) " or "value =
findFile(full_path)"
3. I am not sure of your usage of n, the way i do similiar things is
to build a list and then just get the item i want by index or slicing.
