Indicates the number of bytes from the beginning of the file that should be streamed into cache via a caching stream. This field is only relevant when opening caching streams via AK::IAkStreamMgr::PinFileInCache() and AK::SoundEngine::PinEventInStreamCache(). When using AK::SoundEngine::PinEventInStreamCache(), it is initialized to the prefetch size stored in the sound bank, but may be changed by the file location resolver, or set to 0 to cancel caching.
