title: What is the difference between file:/, file://, file:///
body: <p>Today I saw in a Java application several different approaches to load a file. </p>
  
  <ul>
  <li>file:/ </li>
  <li>file:// </li>
  <li>file:///</li>
  </ul>
  
  <p>What is the difference of these three URL beginnings and what is the preferred way of using them?</p>
  
  <p>Thanks a lot
