Removing sub-controller folder name from URL

Hi,

I have many sub-folders under main controller folder. When I call a controller, the name of the respective sub-folder appear in URL. How can I remove the name of sub-folder from URL?

Thanks

Appears as: http://localhost/index.php/<b>login</b>/my_controller
Should appear as: http://localhost/index.php/my_controller
