What are unlinked files in FrontPage trouble shooting?

[larrys3255]

I am trying to use Front Page to clean up an old web site. There are a lot of
unlinked files. I understand "Links to" but not "Links from".

Links To is the number of pages with links to the page
Links From: is the number of links to other files or pages from the page

An "unlinked" page may have several links to it from pages that are also unlinked.
