    Documentation?
    This class lets you make the upload process even easier by extending the
    CI_Upload class and adding some funtionality named below:
    *1)Upload multiple files in just one shot.
    *2)Creates the path where you want the files to be saved automatically.
    *3)Creates and index.php file in each folder by passing TRUE to the up() function.
    *4)Modify the same preferences that you used to with the original upload class, here is
    the link of the documentation http://codeigniter.com/user_guide/libraries/file_uploading.html.
    Implementation
    *1)Copy this code in the view_file
    <form method="POST" action="" enctype="multipart/form-data">
    <input type="file" name="file_1" size="20" />
    <input type="file" name="file_2" size="20" />
    <input type="file" name="file_3" size="20" />
    <input type="submit" name="test" value="TEST" />
    </form>
    *2)In your controller file copy the code below
    $this->load->library('upload');
    $config['upload_path'] = './uploads'; //if the files does not exist it'll be created
    $config['allowed_types'] = 'gif|jpg|png|xls|xlsx|php|pdf';
    $config['max_size'] = '4000'; //size in kilobytes
    $config['encrypt_name'] = TRUE;
    $this->upload->initialize($config);
    $uploaded = $this->upload->up(TRUE); //Pass true if you want to create the index.php files
    var_dump($uploaded); //prints the result of the operation and analize the data
    */
