The problem there is, is that they aren't actually html pages, they are text
pages without a ext. So in the end the file comes out garbled(all the words

text or not set with any ext at all(the file comes out looking like an html
file. So in the end Httrack isn't doing a clone of the website, but modifies
each file ext as it is downloaded.
