title: set directory to a path in a file
body: <p>I just want to set the directory to a path I have written in a file before.</p>
  
  <p>Therefore I used :</p>
  
  <pre><code>fileChooser.setCurrentDirectory(new File("path.txt"));
  </code></pre>
  
  <p>and in path.txt the path is given. But unfortunately this does not work out and I wonder why :P.
  I think I got it all wrong with the <code>setCurrentDic</code>.. </p>
