When you update an iOS app, what happens to the Documents folder contents?

Question

What happens when I update an app that has some files stored in the Documents folder? I need those files to be kept in that folder so the updated app will be able to use them. But it doesn't seem to happen. Is there anyway I can manage to save all my files?

Answer 1

Your documents will stay where they are - unless the user deletes the app before updating (but that wouldn't be an update..).
