title: Android Studio Corrupted .java file after improper shutdown
body: <p>I hibernated my laptop when Android Studio was running and found later that the laptop had been shut down. Now one of my source files is appearing empty in Android Studio and in Wordpad as well. When I open it in Notepad++, it shows NUL character. The file has the same size as it had before which means that the file content is not lost (hopefully).</p>
  
  <p>How do I recover the actual content of this file? I need this as I didn't have a backup of this file.</p>
