Abstract
A portable multifunction computing device optimizes cache storage when processing media files and the like. During a playback operation, the device caches as many media items as possible such that during playback media items are retrieved from cache rather than from a hard disk memory. The device monitors memory requirements of other programs and applications currently in use on the device to insure sufficient cache memory is available for such programs and applications.
