Ahmed Ismaiel Zakaria has created a Win32 Zip program that supports Zip files, and is promising to soon support JAR, CAB, ARJ, RAR, ACE, and so on. Yes, there are many other programs just like it, but SmartZip appears to be free and the author is promising to release the source code. (Of course, he’s violating the GPL if he doesn’t offer the source code even with these early releases.) This project is posted on the venerable and esteemed CodeProject site, the author appears to be actively working on the project and communicating on the open forums.

Last updated November 6, 2003. Oh, wouldn’t it be grand if the author posted release notes and a shipment history!
