title: Remove all files that start with same prefix, but different filetype
body: <p>How do I remove all files in a folder that start with the same prefix? For example:</p>
  
  <p>I have files:</p>
  
  <pre><code>SVM1.txt
  SVM2.csv
  SVM3.mat
  helloworld.txt
  README.txt
  </code></pre>
  
  <p>I want to delete all the files that start with 'SVM'. Note that they start with the same prefix, but are of different filetype!</p>
