body: <p>HI</p>
  
  <p>Whats the best way to create a random name for a folder?</p>
  
  <p>Its going to be used for a folder name to store documents. But lots of folders are going to be created and so need it to be unique each time if possible.</p>
  
  <p>Length should probably be around 7 characters.</p>
