Specifies how a system identifies the sector locations of files on a physical medium and generally includes other metadata such as a file's size, access permissions, and when it was created and modified. Operating systems generally have their own proprietary file system specifications, but some have been standardized for interchange across operating systems. A journaled file system is one that maintains a log (journal) of activity in the main data areas of the disk, which helps to ensure data integrity in the event of a system crash or other abnormal termination.
