What is DDL? If you mean DDE (dynamic data exchange) I don't think WinZip supports it (or OLE automation, for that matter). That is why my office bought DynaZip (
www.innermedia.com). There are other, cheaper products, usually .DLLs, that will do the job, but they aren't as well supported or documented as DynaZip.
