Hey mike. If all the pages in the site are located in one directory, using that
link should download all files. E.g. mirroring somesite.com/ will download all
links under that directory. You may have scan rules set to limit the depth or
file types to be mirrored; check out <https://www.httrack.com/html/filters.html>
for more details on scan rules. Using +* with no other rules, and making sure
you have no limits set (https://www.httrack.com/html/step9_opt2.html) should 
work. Hope this helps!
