title: Unable to close many buffers by one command in Vim
body: <p>I use Vim in Screen. I run the command</p>
  
  <pre><code>vim &lt;bigFolder&gt;
  </code></pre>
  
  <p>I am in stuck, since it does not make sense to close each buffer by</p>
  
  <pre><code>:q
  </code></pre>
  
  <p><strong>How can you close all active buffers in Vim,</strong> by one command inside Vim?</p>
