title: Is it possible to change file content directly in zip file?
body: <p>I have form with text box and customer wants to store all changes from this textbox to zip archive. </p>
  
  <p>I am using <a href="http://dotnetzip.codeplex.com" rel="nofollow">http://dotnetzip.codeplex.com</a>
  and i have example of code:</p>
  
  <pre><code> using (ZipFile zip = new ZipFile())
    {
      zip.AddFile("text.txt");    
      zip.Save("Backup.zip");
    }
  </code></pre>
  
  <p>And i dont want to create each time temp text.txt and zip it back.
  Can I access text.txt as Stream inside zip file and save text there?</p>
