title: Add a single file to each rar file in a folder
body: <p>I'm trying to figure out how to add a file in each .rar file in a folder.</p>
  
  <p>For example I have:</p>
  
  <ul>
  <li>rar1.rar </li>
  <li>rar2.rar</li>
  <li>rar3.rar</li>
  </ul>
  
  <p>And I want the 'readme.txt' file added to each of them.</p>
  
  <p>Or if that isn't possible I can just extract all the .rar files turning them into folder then use this batch code to compress them?</p>
  
  <p>How do I include the readme.txt file?</p>
  
  <pre><code>@ECHO OFF
  cd C:\Users\userss\Desktop\compressing
  SET PATH=C:;C:\Program Files\WinRAR;C:\Windows\system32;C:\Windows;C:\Win dows\System32\Wbem;%PATH%
  FOR /f "delims=" %%d IN ('DIR /B') DO WinRAR a -m0 -ep "C:\Users\userss\Desktop\destination\%%~nxd.rar" "%%~fd"
  EXIT
  </code></pre>
