Ha - me too. I have some C wrappers around Dynazip that are exposed as Win32 endpoints in wwipstuff.dll and that works fine.

7z has an API but it's a C API that can't be called directly from Fox so you still need to create an FLL, or Win32 wrapper so you can call it. I figure it's just as easy to shell out and use it and the EXE is actually more compact than the API.
