METHOD OF STORING FILE DATA ON DISK

摘要

PROBLEM TO BE SOLVED: To provide a method for efficiently storing file data on a disk storage device in a data processing system. SOLUTION: File data is stored in a number of different representations on disk. File data is stored in streams which may assume any of several different representations. Each stream has an associated stream descriptor which describes how the stream is stored on the disk. The representations include storage of a stream in a single extent, storage of a stream in multiple extents and storage of a stream in an associated stream descriptor. COPYRIGHT: (C)2008,JPO&INPIT
