title: Unable to Git-add with force
body: <p>I get git-status at ~/bin:</p>
  
  <pre><code># Untracked files:
  #   (use "git add &lt;file&gt;..." to include in what will be committed)
  #
  #       screen/dev/
  </code></pre>
  
  <p>I run </p>
  
  <pre><code>git add --force screen/dev/
  </code></pre>
  
  <p>I get the same git-status as before. I add each file in the folder independently, but I get the same git-status.</p>
  
  <p>There is no .git in screen/dev/. The folder seems not to be a sumbodule.</p>
  
  <p><strong>How can you add a folder and its content with force to my git at ~/bin?</strong></p>
