title: iOS and OSX Document Packages cross platform
body: <p>I have a iOS and OSX application which is document based and i am saving complex folder hierarchy inside the document so i change my UTI type to document package.</p>
  
  <p>But the problem is that according to apple <a href="https://developer.apple.com/library/mac/documentation/CoreFoundation/Conceptual/CFBundles/DocumentPackages/DocumentPackages.html" rel="nofollow">Document Package</a> is just a folder. If i open the document package on windows or linux machine it consider it as folder despite of having a .abc extension. I figured out that one solution to this problem is that i zip the folder while saving. But i don't think that it is a good approach because every time i open up the file i will have to decompress the folder and compress it again on re-saving.</p>
  
  <p>Is there any other solution to this problem?</p>
