title: Find files of multiple extensions batch
body: <p>I'm trying to search for files of multiple under a specific directory.
  I know that if I wish to search for all <code>.exe</code> files under <code>C:\Test</code>, I do the following:</p>
  
  <pre><code>set FoundFiles=dir /b /s C:\Test\*.exe
  </code></pre>
  
  <p>But, what I wish to search for all <code>.exe</code> and <code>.txt</code> files under <code>C:\Test</code>? Is it possible in the same way?
  I tried the following:</p>
  
  <pre><code>dir /b /s C:\Test\*.exe *.txt
  </code></pre>
  
  <p>It works in cmd, however, when I do this:</p>
  
  <pre><code>set FoundFiles=dir /b /s C:\Test\*.exe *.txt
  </code></pre>
  
  <p>It doesn't work.</p>
  
  <p>Is it even possible?</p>
