OK, no prob. Didn't know. I was checking the docs http://book.cakephp.org/2.0/en/contributing/cakephp-coding-conventions.html and found nothing there...
Probably this should be added to the docs.

Shall I open a ticket for the docs about that?
I could go forward and add it to the docs but I think someone with a broader view of the standards should go forward and add everything about view files in...
