title: Can't open file under custom folder on my Eclipse project
body: <p>I'm developing a custom plugin for Eclipse and I have a powerpoint file named "extract.ppt" that I want to open through my source code. </p>
  
  <p>When I place the file on my projects root diercotry and use: </p>
  
  <pre><code>File file = new File("/extract.ppt");
  </code></pre>
  
  <p>the file opens just fine.</p>
  
  <p>But since im gonna be using a few more files on my application, I thought it would be a good idea to keep them all organised under a folder. So I created a folder named "files" under my main project folder and tried to use:</p>
  
  <pre><code>File file = new File("/files/extract.ppt");
  </code></pre>
  
  <p>but I get an error saying the file does not exist. I checked my Eclipse project's folder and the folder "files" as long as the "extract.ppt" are there.</p>
  
  <p>Any ideas?</p>
