title: Powershell - if and testpath with not Logic
body: <p>My Code is this:</p>
  
  <pre><code>If (Test-Path c:\temp\mysunnyday)
  {
      New-Item c:\temp\mysunnyday -ItemType directory
  }
  Set-Location c:\temp\mypodcast
  </code></pre>
  
  <p>I wish to say <code>IF NOT TRUE</code>. How can I do that? I read this article</p>
