Finding un-linked or un-used pages and files???

I've stumbled into a project with a website that was generated by some strange piece of programming which resulted in thousands and thousands of files. I've noticed a ton of redundency and I'm very certain a LOT of the files in the folders are never used (or linked to anything).

I'm wondering if there is a program out there that can tell which pages aren't being touched? Something that can start from the main home page and spider through all of them, and then compare the list of valid files to a list of those not linked at all? I'm hoping to delete all unused files and clean this junk up.

Any thoughts??

Pick one the suits your needs.

Dreamweaver can find broken links if you have that program.

Not really broken links, so to speak. More like a file comparison.

A program that starts from the home page and crawls all links, creates a list of all files (htm, gifs, jpgs, pdfs, whatever) that are linked or "touched" by the spider.

Then another process that finds all the files in those folders that aren't touched. Those files might also have links in them, but a person would never hit the page. Its an unneeded file since it can't be reached through any links via the home page or subsequent links from there.

I think I might have found a tool at http://www.lithopssoft.com/hlv/validator_filelists.html which will do the trick in a round about way.

Thanks.
