That depends on how you invoke it: os.system creates a new shell which in turn creates a new process; the spawn* functions do that directly. Anyway, if you have many conversion processes running, you should pass them unique file names to avoid conflicts. Where does the '1' name come from? If it's you, don't use a fixed name - the tempfile module may be useful. -- http://mail.python.org/mailman/listinfo/python-list
