>Yes, I found ZIPIT, it's a free DLL ActiveX but it uses UNZIP32.DLL, I found its original web page and it says that in order to use it (UNZIP32.DLL) with a commercial app we should talk to the author to get a license.

>>>Hi friends!
>>>
>>>I'm looking for a really free Zip/Unzip .DLL or ActiveX control (I'd prefer a .DLL) that is compatible with the standard Zip format. This would be used for an App I'm developing in VFP 7. Any help would be very appreciated. Oh! I forgot, I have the free ZLIB.DLL utility but I can't find a way to unzip a .ZIP file, if anyone has a routine or an idea, it would be better.

>>Check download area. There's a bunch of ZIP/UNZIP tools including free once.
