can't see welcome message

Hi all. I just install Xampp, Codeigniter and Aptana. I am going to localhost/ci_intro and I am seeing this screen. I cannot see the welcome_message in the view folder. I am trying to follow a really old tutorial for codeig. 



I was recommended to learn mvc from old code igniter tutorials because the website I need to modify is based on these.

Where is the file to set default view file? There is no file  config.php in app/config/config.php (maybe this was changed in newer versions
