PERSISTING FILE SYSTEM INFORMATION ON MOBILE DEVICES
First Claim
1. A communication device adapted to store and update file system information for a network resource, the communication device comprising:
- a wireless communication module;
a display;
a persistent memory; and
a processor in communication with the wireless communication module, the display, and the persistent memory, the processor being configured to;
store, in the persistent memory, data comprising first file system information received via the wireless connection module for the network resource;
request, using the wireless connection module, new file system information for the network resource when it is determined that the first 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;
enable receiving data comprising the new file system information using the wireless connection module; and
store said data comprising the new file system information in the persistent memory.

Abstract
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. 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.
