Thanks again, but sorry I still do not understand the second part: 

" "Change local structure to xxx in web/xxx" Where do
RT*M <http://www.httrack.com/html/step9_opt5.html> "

The link given does not appear to mention anything at all about this, so I've
still no idea about what the above means or where or what to enter. 

If Httrack had a manual I certainly would read it. What is available online is
very terse and opaque. 

Thanks
