Add users or groups as owners to multiple files when you need clear stewardship across your policies, procedures, and reference materials in Documents. This endpoint is useful after a team restructure, handover, or repository clean-up. Each file supports up to 5 owners, and this request accepts up to 100 file IDs.
File ownership focuses on accountability and filtering by owner. It does not replace file and folder access controls, which manage who can view or edit files and folders.
