hi xavier, thanks for the reply. okay, so to verify 
what you have said, if i have a project "foobar" with 
one url "www.foo.com/bar/index.html" and i add one 
custom filter "-www.foo.com/bar/*", then basically 
nothing gets downloaded at all? if this is so, then i 
think you have answered my question: httrack's default 
behavior when you remove all filters (built-in + 
custom) is to exclude everything.
