title: renaming files in subdirectories with a DOS-Batch
body: <p>i want a BATch to check if 2 given files are in the directory
  + if they are change their names</p>
  
  <p>so far i have gotten this:</p>
  
  <pre><code>@echo off
  
  if exist %order.xml &amp;&amp; %order.xml.orig goto RENAME
  goto END
  
  :RENAME
  rename order.xml order.xml.old
  rename order.xml.orig order.xml
  
  :END
  pause
  </code></pre>
  
  <p>which works just fine, but the problem is i have to copy this into each subdirectory.
  is there a way to let the BATch check every subfolder? everything i tryed just gave me an syntax-error</p>
