Again. Controller in Sub-folders (new way?)

[eluser]tonanbarbarian[/eluser]
Have you tried this without the routes... because the loader will search in a single depth sub folder for a matching controller
The only time we have found an issue is if you want more than 1 sub folder depth

Code:

application/controllers/main/admin/admin.php
application/controllers/main/admin/user.php

will not work.

Or if you try to do something tricky like

Code:

application/controllers/main.php
application/controllers/main/admin.php

will also not work. This is because you have a controller at the root level the same name as a sub folder

but just to have

Code:

application/controllers/main/main.php
application/controllers/privacy/privacy.php

working requires no effort

It is also unclear from your example why you are putting the controllers into sub folders. I assume there are going to be multiple controllers under the main sub folder and also under the privacy subfolder.
If not then just do not use subfolders.
