title: Can't see project folders in IntelliJ IDEA
body: <p>Every once in a while, I open an old project and I can't see any of the folders in the intelliJ project viewer. I can see all the files at the root.. but no folders. Yes I can delete the .iml file and .idea folder and re-create the project, but come on.. there's gotta be an easier way to fix this.</p>
  
  <p>Is there?</p>
