title: Git Branch newbie - How to reverse?
body: <p>Not sure if this is a proper way to work with branches.</p>
  
  <ul>
  <li>I had this application on structure A.</li>
  <li>I created a branch Z while I was on that structure A (but I kept my self on the master branch working).</li>
  <li>While working (on the master branch), I changed that structure and I end up messing the all thing. :)</li>
  <li>I've never commit nor added those new files to the rep.</li>
  </ul>
  
  <p>Request:</p>
  
  <ul>
  <li>I need to revert to the structure existing on the last commit. Revert All Uncommitted changes and also remove new files and folders that may have been added.</li>
  </ul>
  
  <p><strong>How can this be done?</strong></p>
