title: Batch renaming files to remove prefix and characters in the middle of file name
body: <p>I'm trying to rename a bunch of files on MS DOS and need to remove the prefix &quot;Q0card-&quot; and also remove a string &quot;.psd&quot; before the file extension.</p>
  <pre><code>Q0card-Aurora.College.psd.png
  Q0card-RedBullRacingHonda.psd.png
  Q0card-ROKiTVenturiRacing.psd.png
  Q0card-WaltDisneyWorldResort.psd.png
  Q0card-Zenseact.psd.png
  </code></pre>
  <p>Is there a way to easily do this with a MS DOS command or a batch file script?  I tried using jren.bat but the documentation and examples is lacking and not giving me enough info nor guidance.</p>
