title: join files inside every folder using batch command
body: <p>I have 10-20 directories with a number of files inside in each folder. <br>
  I want to join in a single file every pack of files inside each folder so if I have 20 folders with 2300 files I want 20 joined files.</p>
  
  <p>Example</p>
  
  <pre><code>INPUT
  
  folder1 - 500 files
  folder2 - 340 files
  folder3 - 5 files
  
  OUTPUT REQUEST
  folder1.txt (500 joined files)
  folder2.txt (340 joined files)
  folder3.txt (5 joined files)
  </code></pre>
  
  <p>But I have many folders so I try to find a <strong>.bat</strong> command to create automatically this operations.</p>
