CodeIgniter Folders Overview

I like to focus I like to focus on Application folder, this where we'll be working most of the time as we build our applications. We'll be building controllers, this is a PHP classes that design to take incoming HTTP request , we'll be building view files , this will be html pages or they can be page fragments like headers footers or side bars. There also Error folder, this folder contains a couple of templates

• error_404.php
  
• error_db.php
  
• error_general.php
  
• error_php.php
  

to display various errors types. For instance if you want load "www.DomainOnWhichYouInstallCodeIgniter.com/CodeIgniter/index.php" , you'll see we getting a 404 page. Which happens to correspondent to this template error_404.php.
