I have a site I would like to download - all specs and user manuals for
various welders they've manufactured - and Httrack does the job alright.

 But it turns out each document is a .pdf on (in?) google drive as referenced
by their site.

 So when I browse the downloaded site I get the documents alright but from
google drive again!

 They don't exist on my computer.

 Can httrack be configured to get them and download them? Or there is some
other way/software that will help?
