path stuff

[fscked]

I am walking some directories looking for a certain filename pattern.
This part works fine, but what if I want to exclude results from a
certain directory being printed?

eg

d:\dir\mydir1\filename.txt                      <----------I want to
see this one
d:\dir\mydir2\archived\filename.txt         <----------I don't want to
see anything in the "archived" directory
d:\dir\mydir2\filename.txt                      <----------Again, I do
want to see this one

I am having a bit of trouble figuring out how to use the path module
to hack up the path to determine if I am in a subdir I care about. So
either don show me the results from a certain directory or just plain
skip a certain directory.
