title: unrar a password protected archive in batch
body: <p>I want to use a batch file to automatically extract files from a password protected rar archive.
  I tried this code:</p>
  
  <pre><code>@echo off
  UNRAR E -INUL -P ne2020 "%~dp0program.rar"
  pause
  </code></pre>
  
  <p>but the output that the cmd window that showed to me tells me that unrar aren't an internal/external command.
  how to fix that?</p>
