title: How to replace just first space in file name by a string on multiple files in a directory?
body: <p>Does anyone know how to replace first space in a file name by a text like <code>_TEMP-</code> after the first 8 characters of the file name?</p>
  
  <p>Also I was hoping to write a batch file that can change multiple files in a directory with similar file name structure.</p>
  
  <p>For example:</p>
  
  <p><strong>Before:</strong> <code>12345678 Hello World.txt</code></p>
  
  <p><strong>After:</strong> <code>12345678_TEMP-Hello World.txt</code></p>
