More of a question that problem, I see this often - templates that start with an underscore. For example,
Reading the Craft docs:
Note that if any of the URI segments begin with an underscore ('_'), Craft will return a 404, since template path segments that begin with an underscore are considered "hidden" from direct access
I guess I'm confused as to what I am hiding from. Is it so I can't directly browse right to the full path of that template?
If you move the craft folder outside of the site root, I can't really get to that file can I? It just isn't obvious to me (yet) what the benefit is and when/where/why I need to start a template with and underscore.
