[wp-hackers] Problems recognising templates in the file system

[Kris Young]

Are there strict requirements from WordPress in regards to identifying
and using templates within the file system? Two problems have come up
since trying to organise my file structure a little better - I'm a
stickler for tidy dev environments, and comprehensive file structuring.

Arranging templates into a new folder under the root theme folder has
stopped WP from recognising them. The same goes for moving them back
into the default theme folder and renaming those templates with a hyphen
(so template-blog.php, rather than with an underscore). Undoing both of
these changes fixes the problem, but I want either of those two changes
I made to stand. Preferably both, actually.

Any way around this problem?
