.. describe:: File System Manager

    A set of OS Services that provides Files and Directories for user
    applications.

.. describe:: File

    A named, ordered collection of information

.. describe:: File System

    A set of files and directories contained on a single drive.  The 
    raw data on the drive is translated to this abstract view of files and
    directories by the file system manager according to the specification of
    the file system standard.

The file manager administers the file system by:
    * Storing the information on a device
    * Mapping the block storage to a logical view
    * Allocating/deallocating storage
    * Providing directories
