Folders (formerly known as Bundles) are a powerful way to share many documents with a single link. In order to get the most out of this feature, folders can be updated, i.e. documents can be added and removed. This will help you to keep the team updated on the latest progress or your accountant up to date with the latests bills. These features are available on both iOS and Mac apps. The screenshots below will guide you through the process of updating folders.
