title: Eclipse Android Imported existing projects Accidently replaced and project all gone
body: <p>I updated the ADT and imported the projects. Unfortunately, I replaced the projects/folder.
  All of sudden, all the files in the folder became 0 bytes, including files in sub folders and all the current auto backups. Is there any other way to recover?and why this all 0bytes happened?</p>
  
  <p>I had tested decompiling my apk from mobile with <a href="https://stackoverflow.com/a/6081365/1009225">this</a>  and Differente decompilers. but, couldn't all the codes and obstucted codes. and most of the decompiler resulted errors.</p>
