title: Using WiX to package an installer with many files
body: <p>I have a WiX 3 project that has hundreds of files, and I can't seem to figure out how to include them all using a wildcard. I have tried this:</p>
  
  <pre><code>heat.exe" dir ".\!Build" -gg -ke -template:fragment -out "Files.wxs"
  </code></pre>
  
  <p>This produces a fragment .wxs file, but I'm not sure what to do with it. Any help would be much appreciated.</p>
