title: How to recover a notebook emptied after kernel crash?
body: <p>While working in an ipython notebook, eventually I had to Ctrl+C as the kernel seemed to be halted.</p>
  
  <p>The console gave me a message like:</p>
  
  <pre><code>[NotebookApp] Kernel  shutdown: 5faa86bf-........f6 
  [NotebookApp] Kernel  shutdown: 71........22 
  [NotebookApp] ....
  </code></pre>
  
  <p>(I had three notebooks running)</p>
  
  <p>But something went wrong and my notebook file.ipynb is empty (actually only the one I was actively using).</p>
  
  <p>Is there a way to recover that file before it was deleted? Some place where automatically-saved o manually-saved versions are stored?</p>
  
  <p>(Running python 2.7 (Anaconda) in Windows 7)</p>
