The reason for running share is protect the FAT and the data on your hard disk
from corruption.  The usual way for recent programs to access dos files is 
through the use of handles assigned by dos.  In the first version of dos there
was no such service.  At that time, files were access through File Control 
Blocks (FCB).  File handles were introduced in ver. 2.0.  In order to stay
compatible with users of ver 1.0, some authors continued to use FCB's.  In
fact, SIDEKICK still uses them I think.  If one of these programs is run
in a partition larger than 32 megs. it will corrupt the FAT and make all
data in that partition unavalible.  Programming to prevent this damage is
included in SHARE.EXE along with other code for use with shared files.

If you just copy SHARE.EXE over into your root partition (or where you
keep COMMAND.COM), it will be automatically loaded when necessary without
any further action by you, when you boot the computer.
