Okay, sorry, I wasn't particularly clear on that.

I'm trying to save a bunch of HTML files to disk (I'm using DownThemAll to
save the files as HTML files). The HTML files each have a bunch of links. I
want to then use HTTrack to mirror the links on each of the HTML files.
However, each of the HTML files have links that point to files on the C drive,
instead of the original directory (since their HTML files have relative links)
