title: SevenZipArchiveException: Invalid archive. open/read error
body: <p>I got the following error when I try to extract a zip file:
  "SevenZip.SevenZipArchiveException: Invalid archive: open/read error! Is it encrypted and a wrong password was provided?
  If your archive is an exotic one, it is possible that SevenZipSharp has no signature for its format and thus decided it is TAR by mistake."</p>
  
  <p>Nothing works with zip files, but everything works fine with 7z files. Is it possible to extract zip files with the SevenZipExtractor?</p>
  
  <pre><code>string sourcePath = @"c:/temp/yyy.zip";
  using (var file = new SevenZipExtractor(sourcePath))
  {
     file.ExtractArchive(outputPath);
  }
  </code></pre>
