Data pertaining to a folder structure or content listing is received at the device and stored in persistent memory. Upon determination that the stored file system information has aged beyond a predetermined threshold and that a last modification time for the network resource is later than a time associated with the first file system information, a request is transmitted over a wireless connection for new file system information for the network resource. The request may be intercepted by a mobile data server that communicates with the network resource to provide the information to the communication device."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Persisting file system information on mobile devices","description":"A communication device and method are provided for storing and updating file system information for a network resource such as a content server or application server over a wireless connection.
