title: Load local files using iframe
body: <p>I tried to load some files using <code>iframe</code>, but it didn't work.</p>
  
  <p>I want to load a file from: <strong>C:/Users/Tom/Desktop/Courses/c2.pdf</strong> and 
  I tried:</p>
  
  <p><code>&lt;iframe src="file:///C:/Users/Tom/Desktop/Courses/c2.pdf"&gt;&lt;/iframe&gt;</code></p>
  
  <p>but nothing appears.</p>
  
  <p>How can I load local files using <code>iframe</code> or something else?
  Thanks.</p>
