title: Directory error in Intellij
body: <p>So, I've been trying to create a resource folder/directory for my java project in Intellij IDEA. For some reason I can't actually get this to work.  </p>
  
  <p>So now I go to create a directory under my helloworld package  </p>
  
  <p>and this error message shows up "failed to create directory (x location)"</p>
  
  <p>but I go to check my folder where all my other stuff for the project is stored, and there is a folder there with the exact same name. Anybody got any idea what's going on here?</p>
  
  <p>(I'd post pictures but apparently I need 10 reputation?? which I don't have. Sorry.)</p>
