This example shows how to change the default directory for changing where classes are extended, specifically here to extend Controller_CI - I have used CH to denote CHILD class

In boot:

if (is_dir('<path>/extend/codeigniter_CH/')) {
    define('APPEXTEND_PATH', '<path>/extend/codeigniter_CH/');
} else {
    exit("<br />Error<br /><br />Your application extend folder path:<br />" . APPEXTEND_PATH . "<br />does not appear to be set correctly. Please open the following file and correct this: " . SELF);
}

in Controller.php class (system) at line 230 of orig file

if (file_exists(APPEXTEND_PATH . config_item('subclass_prefix') . 'Controller.php')) {
    require APPEXTEND_PATH . config_item('subclass_prefix') . 'Controller.php';
} else {
    exit("not found " . APPEXTEND_PATH . config_item('subclass_prefix') . 'Controller.php');

}

Codeigniter looks for library in application/library 1st, then system/library. You have only these two options. The folders are given for that purpose.
