  58 <h1>Auto-loading Resources</h1>
  59
  60 <p>CodeIgniter comes with an "Auto-load" feature that permits libraries, helpers, and models to be initialized
  61 automatically every time the system runs. If you need certain resources globally throughout your application you should
  62 consider auto-loading them for convenience.</p>
  63
  64 <p>The following items can be loaded automatically:</p>
  65
  66 <ul>
  67 <li>Core classes found in the "libraries" folder</li>
  68 <li>Helper files found in the "helpers" folder</li>
  69 <li>Custom config files found in the "config" folder</li>
  70 <li>Language files found in the "system/language" folder </li>
  71 <li>Models found in the &quot;models&quot; folder</li>
  72 </ul>
  73
  74 <p>To autoload resources, open the <var>application/config/autoload.php</var> file and add the item you want
  75 loaded to the <samp>autoload</samp> array. You'll find instructions in that file corresponding to each
  76 type of item.</p>
  77
  78 <p class="important"><strong>Note:</strong>  Do not include the file extension (.php) when adding items to the autoload array.</p>
