How do you delete a DragonVale file?

To delete a DragonVale file, first, locate the app on your device. If you're using iOS, you can delete the app by pressing and holding the app icon until it wiggles, then tapping the "X" to remove it. For Android, go to Settings > Apps > DragonVale, and select "Uninstall." Keep in mind that deleting the app will remove all associated game data unless it's backed up to a cloud service.
