title: groups and files in XCode vs. project folders in Finder
body: <p>I still can't get the idea that when I create a new Group in XCode, and build the project, and then return back to finder and notice that the group does not exist but any file to be created under this group will appear in the project's directory in finder but that file is alone without being under any group.</p>
  
  <p>(note: I'm not talking about this directory: /Users/<em>username</em>/Library/Application Support/iPhone Simulator/4.3/Applications/<em>uuid</em>/...)</p>
  
  <p>1) can anyone explain why project's directory hierarchy in finder is different from the project's directory hierarchy in XCode ?
  2) how can I make the two hierarchies looks like exactly the same between XCode and Finder? so when I create a new Group in future I can see it in finder.</p>
  
  <p>thanks in advance.</p>
