Filesystem Crawl for Page Text Output?

I have a large web site with .html files in many places. I would like
to
find a script or product that would crawl the site root (as a local
filesystem) and create a "pretty" text file showing the
directory/folder structure of each file (html and js files
only). I was playing around with linklint but I can't
seem to get it to do what I want.

Thanks.
