A user interface for a virtual file management system that provides user access to managed content on mobile devices. The system comprises storage domains storing the managed content distributively using file systems, and a data infrastructure that organizes the managed content into a virtual file system. The data infrastructure includes a component that maintains policies defining controls for permissible operations on the managed content, the permissible operations including the file system primitives. A client application including a user interface is hosted on the mobile devices and is coupled to the data infrastructure and the storage domains and includes an enforcement component that retrieves and enforces the policies by applying the controls on the mobile devices.
