title: Unzip files (7-zip) via cmd command
body: <p>I try to unzip a file via CMD.</p>
  <p>So I install winzip (and its plugin to cmd), winrar and 7-zip.</p>
  <p>But when I try to <a href="http://www.dotnetperls.com/7-zip-examples" rel="nofollow noreferrer">execute a command</a> via the CMD:</p>
  <pre><code>7z e myzip.zip
  </code></pre>
  <p>It gives the next error:</p>
  <pre><code>7z is not recognized as an internal or external command
  </code></pre>
  <p>In addition, I added the folder of 7-z to the environment variables (Properties--&gt; advanced --&gt; Environment Variables --&gt; user variable --&gt; choose path, and add <code>C:\Program Files\7-Zip</code></p>
  <p>What can be the reason?</p>
