title: Git checkout -- recover lost files
body: <p>I accidentaly deleted local file changes on git repository. They were NOT commited or even pushed.</p>
  
  <p>What I did:
  <strong>git status</strong> 
  (then files not staged for commit showed and I accidentaly removed whole folder called "smdr" by this comand):
  <strong>git checkout -- smdr</strong></p>
  
  <p>Then files changes disappeared.</p>
  
  <p>How can I recover those files (birng everything back before that git checkout -- smdr comand)?</p>
