Abstract: A system and method for recursive propagating application access control relate to managing third-party application access to content files and folders on a cloud storage system. The access control system may receive an access authorization indication to grant a third-party entity access to a parent folder containing a first file, and then modify an access control rule associated with the parent folder based on the access authorization indication. The modified access control rule is propagated to a child folder of the parent folder, and thus the third-party entity is granted access to a second file in the child folder based on the modified access control rule. The second file shares a common attribute with the first file, and the modified access control rule specifies the common attribute.
