body: <p>I have a folder in my project. And inside that folder are files that my program is going to read from at run-time (i.e. most important one of them). So if the folder name is "xyxyxy" and if I am looking for the file "zzz.xml" in that folder I can access that file by </p>
  
  <pre><code>if (File.Exists(Environment.CurrentDirectory + "/xyxyxy/zzz.xml"))
      MessageBox.Show("File found!");
  else
      MessageBox.Show("Not found!");
  </code></pre>
  
  <p>How can add this entire folder to the bin folder (both in debug and release)?</p>
