title: Git: how to switch from branch X to Y?
body: <p>For example, I clone step_06 of:</p>
  <blockquote>
  <p>git clone -b step_06 <a href="https://github.com/Urigo/meteor-angular-socially" rel="nofollow noreferrer">https://github.com/Urigo/meteor-angular-socially</a></p>
  </blockquote>
  <p>Now I want to replace step06's files with step07's files (on my machine).
  So I did:</p>
  <blockquote>
  <p>git checkout -b step_07</p>
  <p>cd meteor-angular-socially</p>
  <p>git checkout -b step07</p>
  <p>Switched to a new branch 'step_07'</p>
  </blockquote>
  <p>However <strong>nothing actually changes in the folder/files</strong>.</p>
  <p>What am I doing wrong?</p>
