title: Laravel 5 Class 'App\Http\Controllers\File' not found
body: <p>i get the following error:</p>
  
  <pre><code>Class 'App\Http\Controllers\File' not found
  </code></pre>
  
  <p>when using in laravel 5 Controller: </p>
  
  <pre><code>$files = File::files( $this-&gt;csvDir );
  </code></pre>
  
  <p>I have to add the <a href="https://github.com/illuminate/filesystem">Filesystem</a> to <code>composer.json</code> and <code>config/app.php</code>. Somehow I use a misconfiguration. </p>
  
  <p>That's what I changed: </p>
  
  <h3>composer.json</h3>
  
  <pre class="lang-javascript prettyprint-override"><code>    "require": {
          "laravel/framework": "5.0.*", 
          "illuminate/html": "5.*",
          "illuminate/filesystem": "5.*"  /* my try to repo */
      },
  </code></pre>
  
  <h3>config/app.php</h3>
  
  <pre class="lang-php prettyprint-override"><code>    'providers' =&gt; [
  
      // [...] 
      // jerik 2015-04-17: get html Forms
      // http://laravel.io/forum/09-20-2014-html-form-class-not-found-in-laravel-5
      'Illuminate\Html\HtmlServiceProvider', 
      'Illuminate\Filesystem\FilesystemServiceProvider', // try to add file
  </code></pre>
  
  <p>When I run <code>composer update</code>, it runs well, but there is no ouput that the Filesystem is downloaded. So my configuration is wrong, but I do not know the correct way. </p>
  
  <p>Any suggestions or tips?</p>
