title: iPython notebook not loading: too much output
body: <p>I have an iPython notebook file which is not loading, presumably because there is too much output in the file (thousands of lines of results printed, old computer).</p>
  
  <p>I can edit the file with notepad without problems, but copying and then cleaning the code from there cell by cell is very time-consuming.</p>
  
  <p>Is there a way to recover the code differently, or to ask iPython notebook to only load the code and not print all the past outputs when opening the file?</p>
