When it comes to the domain names you use for free sites and galleries, do you add a listing in the site map for each and every directory, so far example, if you have 100 free sites on a domain name, do you list all 100 sub directories for those free sites in your Google sitemap file?

I was reading that you process up to 50k individual urls inside a sitemap file but wasnt sure if it mean directories or pages, etc?
