title: Android Studio: How to 'Refresh' after adding file?
body: <p>I am trying to add a layout to an Android project:</p>
  
  <p>Right clicked on <code>res</code> folder <code>New | Directory</code>. The directory was created however not shown under <code>app/res</code>. Maybe because empty dirs are hidden by default? Went to Windows explorer and added a file to the newly created directory (hidden in Android Studio). Back in the Studio, how can I 'refresh' the project structure to show the newly created directory and the file under it?</p>
  
  <p>Essentially my question is, what is the alternative to Eclipse' Refresh menu option?</p>
