Google webmaster tools is reporting some/many 404 urls that don't exist on my site. The links are things such as domain.com/xyz/ However that doesn't exist, but domain.com/xyz/index.html does exist. The "linked from" pages all show proper links to the "/xyz/index.html".

The page without index.html DOES 404, but why is google even trying these urls if they are not linked to?

My real question, is there a way to have google stop attempting to load these pages, and ultimately remove these from the crawl errors report. Thanks.
