Thank for the detailed reply John! I guess it turned out to be a bit tougher than I originally thought :-)....
Reading over your links, I think I better not attempt rewriting the zipfile.py program... a little over my head :-). The best solution, from everything I read seems to be calling an unzipper program from a subprocess. I assume you mean using execfile()? I can't think of another way. Anyway, thank you very much for your help, it's been very educational. Best regards, Lorn -- http://mail.python.org/mailman/listinfo/python-list
