Multi Level controller not working

[eluser]jaswinder_rana[/eluser]
I just tried it with 2 different structures

1)

controllers/admincp/config/countries

Code:

//Tested with http://localhost/index.php/admincp/config/countries
///Not sure if it's correct but it din't work
$route['admincp/config/countries'] = "admincp/config/countries";

2)


controllers/admincp/countries

Code:

//Tested with http://localhost/index.php/admincp/config/countries
//Worked
$route['admincp/config/countries'] = "admincp/countries";

But, I was hoping to keep structure like 1) and still be able to make it work. It's not working as I have sub-sub-level.

Sorry for being dumb but I can't make it work

EDIT: I am assuming routes.php is for URI management and not for folder, hence won't work for me??
