Song Data Conversion & Preservation (iOS, iPad OS only)

  • From version 3.1.0, this app started using new SongData format.

    In order to make SongData (.iwm) shareable on different platforms, any Song Data created before this version must be converted to the new format when it is loaded on version 3.1.0 or later.

  • Data Preservation

    Because this is a big change, we have tested extensively to make sure everything works properly, however, because of the nature of what it is, it is hardly possible for us to confirm it is 100% safe although it is 100% safe as far as we know (as of 2020/12/19).
    So, when the app overwrites your existing Songdata created with previous versions, you'll be asked if you want to preserve it. You'll have a choice of: Always Preserve, Always Ask, Never Preserve, which you can change later in Application Settings. Preserved SongData won't be updated any more, but will be helpful to recover it in case something unexpected happened.

  • Data Backup

    As always, making backup of your important SongData is strongly recommended.
    The easiest way to make backup is:

    • In FileListView, select Edit (top left) to go to Edit Mode.
    • Select all files you want to make backup.
    • Select Email from the screen bottom, then email them to yourself.
    • If you have a computer, open the email and save all the attached files to somewhere safe.
    Then you can import them back to iWriteMusic whenever you need.
    Most importantly, by doing this, you no longer need to worry about Data Preservation.

  • How to find Preserved SongData

    You can't directly access those data in iWriteMusic.
    To find them, you need to connect your device to Mac or any other computer that can run iTunes so you can use File Sharing feature. Then, you can find PreservedData folder like below. Although you can't open the folder in the view, you can Hold + Drag to somewhere else such as Desktop or Downloads. You can delete this PreservedData folder as you need. The folder will be recreated when iWriteMusic needs it.
