title: Cannot clean internal memory after failed installation
body: <p>I was testing a game of 300MB. I tried to deploy it from the IDE (IntelliJ in this case), but forgot to leave 600MB of space (when a file is installed via Eclipse or IntelliJ, it gets transfered into internal memory). The installation failed with an error "Not enough space on the device" and now I only have 31MB of free space. </p>
  
  <p>How can I clean this as I cannot do it from the phone? Is there a way to delete this transfered file from Eclipse or ADB?</p>
  
  <p>I tried removing battery, cleaning applications' cache and data, etc. All in vain. </p>
  
  <p><strong>UPDATE</strong><br>
  I used ADB shell to enter the file system. This is output of <code>df</code> command</p>

  <p>It seems that I would have to clean /cache directory but the system does not allow me</p>
  
  <pre><code>$ purge /cache
  purge: permission denied
