Why the ".0.html" in all of your pages?

Guys I'm curious as to why all Blacknights pages end in .0.html

http://www.blacknight.ie/support.0.html
http://www.blacknight.ie/hosting-ireland.0.html
http://www.blacknight.ie/register-domain-name.0.html
etc etc

Is it somehting to do with seach engine optimisation or something? Can't say I've seen it on very many other sites...

It's due to the way the web developers setup the CMS originally.
It is possible to output the pages as .html, but by the time they told us Google had already reindexed the site with the 0.html extension....
