I want to create application with structure:

\app\controllers\
\app\controllers\security
\app\controllers\products
\app\models\
\app\models\security
\app\models\products
\app\views\
\app\views\security
\app\views\products

Just for keep clean the root directory

not a modules project, just a folder organized project.

from this post https://forum.phalcon.io/discussion/237/controllers-in-subfolders

i get 

$router->add(
    "/security/:controller/:action",
    array( "controller" => 1, "action" => 2, "namespace" => "Application\SECURITY\\")
);
$router->add(
    "/products/:controller/:action",
    array( "controller" => 1, "action" => 2, "namespace" => "Application\PRODUCTS\\")
);

how to make with models and views sub-folders?

Thanks in advance
