Tim Golden has a method to watch for changes in a directory on his website: http://tgolden.sc.sabren.com/python/win32_how_do_i/watch_directory_for_changes.html This old post also mentions something similar: http://mail.python.org/pipermail/python-list/2007-October/463065.html And here's a cookbook recipe that claims to do it as well using decorators: http://aspn.activestate.com/ASPN/Cookbook/Python/Recipe/426620 Hopefully that will get you going.
