Okay so I've been using HTTrack for a little bit and so far I really like it
for download websites. However what I'd like to know is how do I download
specific parts. 

I followed this guide <http://httrack.kauler.com/help/Filters>

Yet still can't figure this out

An example of what I'm trying to do is say download a specific youtube channel
or maybe my deviantart favourites galley. How would I do that.
