[SOLVED] How to select default controller in subfolder?

Hi community,

I'm trying to do a project in Codeigniter 3.x, but I have a question concerning the routes.

If I have the following structure

/application/controllers/Welcome.php

I can put the following in routes.php and have no problem

PHP Code:

$ route ['default_controller'] = 'welcome'; 


The problem is that if I have the following structure

/application/controllers/admin/Welcome.php

I am not allowed to configure the routes so

PHP Code:

$ route ['default_controller'] = 'admin/welcome'; 


There is the ability to set default controller in a subdirectory of controllers?


Thank you!
