ZIP files *do* start with a magic number; either PK\03\04 (non-empty archive) or PK\05\06 (empty archive). This is rather easy to notice, as I did in the bad old days of DOS, and i recently doubly verified it ('zip'+'khexedit', and http://en.wikipedia.org/wiki/ZIP_%28file_format%29; I tried the infozip website too, but it seems to be down.) _______________________________________________ Python-Dev mailing list Python-Dev@python.org http://mail.python.org/mailman/listinfo/python-dev Unsubscribe: http://mail.python.org/mailman/options/python-dev/archive%40mail-archive.com
