Abstract
A data processing apparatus configured as a browser (70) is described for use with a distributed database management utility (72) which handles the accessing of data defining virtual environments via the Internet/World Wide Web (74). Both browser (70) and management utility (72) maintain copies of data files obtained via the Web and passed to the browser, with a memory management stage (80) detecting when apparatus memory reaches a predetermined level of fullness. Based on a stored and system-updated table (84) identifying the passing of data files from management utility to browser, the memory manager (80) identifies which of the management utility held copies of the files to delete in order to create memory space.
