Right.

However, as per my original post, you'll notice that I included a link to a
PDF document located at the following URL: 
<http://www.lg.com/us/support/products/documents/42CS560.pdf>

So basically, these files are getting stored in the documents folder, and if I
let HTTrack run long enough, it starts to eventually download some PDF files
from that folder. 

There has to be a better way of setting up HTTrack to download just pdf files
from that folder and nothing else, because there are certainly files located
in that directory.
