Finally I have a real use for the "File Sharing" feature in iTunes, to copy a database file from my Mac to my iPhone.
But once added, should iTunes automatically keep that file up to date on the phone, if modifications are made on the Mac file? Or if I want changes to be reflected, do I actually have to delete the file and re-add it? (If the latter that's a pretty big chore.)
There's not even a manual "Update" button; just "Add..." and "Save to...". For that matter there's not even a "Remove..." button!
