title: Store codeigniter libraries in sub folders
body: <p>Is it possible to store libraries in sub folders in codeigniter? For example would something like this work?</p>
  
  <pre><code>-libraries
  ---sub_folder1
  -----someClass.php
  ---sub_filder2
  -----someClass2.php
  </code></pre>
  
  <p>If it does how should I load and use these libraries?</p>
