Web Based partition

[Orenk9]

Hi,

I've a question about the content of the 7zip files:
My application consists of a few dlls and some exe's.
I also defined .net 2.0 and Windows Installer 3.0 as pre-req.

When I build a web based verion of my installation I get 4 files:
the main exe setup file
7zip file for .net 2.0
7zip file for Windows Installer
and - 7zip file with my application name.

My question is: what does it contain? I could tell by its size it does not contains all my dlls. more likely the main exe contains them.
So I could not figure out what it's good for.

Thanks,

Oren.
