By default with WinHTTrack projects are created in "C:\My Web Sites".  That
folder can contain an index.html listing the projects.  Each project folder
can also have an index, usually a redirect to the "start" page of the
project.

The reason you don't get a project index is probably due to HTTrack not
knowing that you have a collection of projects (ie. each time you run the app
it thinks it's a standalone project).  Could be because you're not using -O,
or something similar.

I don't know the exact reason though. ;)
