title: C# with SharpZipLib - Compatibility of SharpZipLib with Winzip and XP?
body: <p>I am using the <a href="http://www.sharpdevelop.net/OpenSource/SharpZipLib/Default.aspx" rel="noreferrer">CSharpZipLib</a> library to automatically zip some files.  The problem is that the resulting zip file doesn't work with Winzip (version 8.1) or XP's compressed folders.
  It does work with 7zip.</p>
  
  <p>Winzip gives an error that <strong>this file is not in the standard Zip 2.0 format</strong>.</p>
  
  <p>Is there a parameter that I can change that would get the library to compress in a Winzip/XP compatible format?</p>
