OK, so make a function of the current program logic for a single filename, and make the base filename a parameter to that function. Then write another function (or main program) that iterates over your directory tree and calls the processing function for each input file. See documentation for module os, specifically os.walk(). (See here: http://docs.python.org/library/os.html ) If that doesn't get you going then post back again. Walter
