Apple's Document Provider extension allows third-party applications to open files from Box (or any cloud storage provider) and save them back to Box without any special integrations within Box. Once you install the Box app on the iOS device, Box shows up as a Document Provider in the Apple UI.
The Document Provider extension allows third-party Box apps (for example, Microsoft Excel) to access documents managed by Box.
The Document Provider consists of two view controllers:
- Document Picker: Displays the Apple user interface when third-party users access a Box document. In this article, we refer to Box as the Document Provider. The third-party app invokes the Document Picker.
- File Provider: Allows third-party users to select, preview, download, or upload Box documents.

The Open files in external applications setting allows Admins to control the user's ability to open content from Box in other applications from the same device. See Mobile Security Settings for more information.
The Allow files to be opened into applications that save back to Box (iOS only) setting allows the document picker to open files from Box in external applications and save changes back to Box.
