How do I save only pdfs, and put them all in one single folder only on my
computer rather than mirroring the site structure, while spidering all the
pages down from the URL I provide?
And is there anything I can do, apart from uninstalling and reinstalling
HTTrack, so that I can completely reset and delete all projects so that I can
get rid of the one I've made a mess of? 

Thanks

ps great software.
