I have semi-automated list generator that output .txt file with 100 URLs:
site.com/image1.jpg, site.com/image2.jpg and so on.
But source from that I'm downloading information often has less than 100
unique URLs - so last file that you can access is image70.jpg or somewhat like
that.

How do I set HTTrack to end downloading after discovery of first file that do
exist on list but do not exist on site?
