Local Area Network-Based File Sharing Procedure

      Disclosed is a process by which data files with little use on a
client machine are automatically archived to a file server.  The name
of this procedure is the Local Area Network (LAN)-Based File Sharing
Procedure (LBFSP).

      Machine performance and machine cost are key concerns for
managers of data processing organizations.  As more data is
processed, PC hard drives fill up and cost per machine to keep up
with the growth increases.  Files can be placed on a server, but
because performance is impacted during data access, highly utilized
files cannot be stored remotely on a file server.  LBFSP was
developed to help alleviate this problem.

      LBFSP is a file monitor transaction that monitors the hard
drive utilization on a LAN client machine.  When the hard drive
reaches a 90% full condition, LBFSP searches the hard drive and
locates files that have low utilization and archives these files to a
LAN file server.  A table keeps a record of this transfer and the
files are erased from the client hard drive.  When the file is
requested and not found on the client hard drive, the table is
checked to see if the file was archived to a LAN file server.  If so,
the data is accessed through a remote procedure call to the LAN file
server.  If the file is requested twice within ten minutes, the file
is placed back on the client hard drive and removed from the LAN file
server machine.

      When LBFSP, a background task initialized at machine boot time,
is started, it creates a File Location Table (FLT), which identifies
files that have been archived.  The format of this Table follows:
