title: vim creates copies of my files after saving?
body: <p>HI there,</p>
  
  <p>Using vim and whenever I make a change and save a file vim seems to create a backup file. I can see that it's the file before I made my change and saved.
  How can I prevent this or hide these files? </p>
  
  <p>I type <strong><em>:wq</em></strong> to save and quit.</p>
