Is there ever a time when the original `e` could evaluate True, yet not startswith(os.extsep)? In other words, could the first test be just if e: e = e[len(os.extsep):] Also, note that for truly maximum portability one probably needs to add to the code some knowledge of case-sensitivity and do a .lower() when appropriate, as "txt" and "TXT" (and others) are equivalent on Windows file systems. On that note, is there a common idiom for detecting that information? -Peter -- http://mail.python.org/mailman/listinfo/python-list
