title: Why can't Windows 7 extract files from my password protected zip-file created using DotNetZip?
body: <p>I'm creating a password protected zip-file using <a href="https://dotnetzip.codeplex.com/" rel="noreferrer">DotNetZip</a>. When I try to extract the files I'm met with an "unspecified error". Why is that?</p>
  
  <pre><code>using (var zipFile = new ZipFile())
  {
      zipFile.Encryption = EncryptionAlgorithm.WinZipAes256;
      zipFile.Password = "pangolin";
  
      foreach(var file in someFileCollection)
      {
          zipFile.AddEntry(file.Name, file.Stream);
      }
  
      zipFile.Save(aPathOnDisk);
  }
  </code></pre>
