Use Sitemap Generator to extract all the links from your site recursively and
generate Google Sitemap (XML), Yahoo Sitemap (TXT), HTML and CSV sitemaps
automatically. Although the program isn't very simple, the way it generates
the map is simple: it acts like a web-spider. When you give the starting url
to the tool, it will start crawling your site, extracting all the links from
all the pages. (in Internet)
