Zip class library for .NET developers

Posted by Mark Nelson on 16th August 2005 | Permanent Link

Ever heard of Resco Mobile Solutions? If you have, you are a step ahead of me. These guys are developers of a variety of programs for mobile devices, and their target platforms include Palm, Symbian, and Windows Mobile devices. They have announced that they are shipping a .NET class library with full support for Zip files. It looks like a pretty complete package, and although these guys are targetting mobile developers, there is no reason you can’t use this on desktop and server systems as well.

This stuff is a bit pricey, but maybe it’s worth it you get decent support and bug fixes. You can download the package and try it out without coughing up any hard-earned cash. If you do, please post your comments here.
