title: is it possible to find hidden files on website?
body: <p>If I'm hosting a website, say at <a href="http://www.example.com" rel="nofollow">http://www.example.com</a>, how can I find files that are in the same folder as <code>index.html</code> if I DON'T know the filenames?</p>
  
  <p>So for example, if there are these files in there:</p>
  
  <pre><code>http://www.example.com/test.txt
  http://www.example.com/test1.txt
  </code></pre>
  
  <p>Can anyone see this list of files? If so, how can I hide them, but make each one accessible to someone who knows the names? I don't want to use a password system, if possible.</p>
