That's not 100% true, you can store an NSFileWrapper that contains a Core Data store as well as other files, so you can store whatever data you like. See this sample code for an example: http://developer.apple.com/mac/library/samplecode/PersistentDocumentFileWrappers/ It's not perfect but it certainly works. For the OP, as Quincey pointed out, your question is not clear.
