title: How to rename multiple files at once and replace specific characters without affecting other characters
body: <p>I want to replace the first two numbers on these 98 files that looks like this</p>
  
  <pre><code>10 10HZ.mp3
  11 11HZ.mp3
  12 12HZ.mp3
  </code></pre>
  
  <p>with "Bass Mekanik - " and make it look like this</p>
  
  <pre><code>Bass Mekanik - 10HZ.mp3
  Bass Mekanik - 11HZ.mp3
  Bass Mekanik - 12HZ.mp3
  </code></pre>
  
  <p>I've tried a lot of different combinations on CMD like this</p>
  
  <p>*rename "?? ????.mp3" "Bass Mekanik - ????.mp3"</p>
  
  <p>But nothing works. I want to keep the last 4 characters on every file.</p>
  
  <p>Also in the near future I will need to add "Bass Mekanik - " in front of every file (not on these files, other files that have a lot of other characters) without changing anything else. So far I learned how to remove the first 2 characters using</p>
  
  <p>*rename "?? ????.mp3" "// ????.mp3"</p>
  
  <p>Then I tried adding "Bass Mekanik" but it gives an error "A duplicate file name exists, or the file
  cannot be found."
  I hope this is possible ...</p>
