Total noob lookin' for some help...

Hi,
I am all new to this framework(to php/frameworks all together) and looked at some beginner tutorials like the one at capsizedesigns but am having a hard time wrapping my head around it.
Even the installation was kind of tricky.
But then I was finally ready to go and played around with some code I found in the Wiki:

http://codeigniter.com/wiki/Listfiles/
What I am trying to do is list the files of a directory on the welcome page.

I changed the welcome.php to:

Code:

class Welcome extends Controller {

    function Welcome()
    {
        parent::Controller();    
    }
    
    function index()
    {
    $this->load->library('listfiles', array('php','jpg', 'jpeg', 'csv'));
        $data['files'] = $this->listfiles->getFiles('./');
    
    
    $this->load->view('welcome_message',$data);
    }
}

And in the welcome_message.php I tried following:

Code:

<?php echo $files ?>

I also added the code to -> application/libraries/Listfiles.php.
But of course it wont work.

Could someone please give me a hint/some code how to solve this?

Thanks in advance.
Cheers
