zip functionality is stored in zipfldr.dll which is a COM library.
In Windows, althuogh there are ways to use the COM interface for unzipping
files, zipping is somewhat harder. I suspect this is hidden as the zip
decompression algorithm used by MS is actually patented and they licence it
from elsewhere.

I've already looked at using alternatives to this for us, and I have a copy of
the lmza.dll library used by 7zip building on my local machine (with VS)
This too is a COM library, and could be adopted as our zipfldr.dll. Also, with
an extension to the COM interface for .zip MS uses, we could also have native
support for .7z, .tar, .iso, .rar, etc.
