                 DEFRAGMENTING A DOUBLESPACED DRIVE
        
        The DoubleSpace DEFRAGment command is used on a DoubleSpaced
        compressed drive. The program doesn't really defragment the
        drive, however it does consolidate the free space.   Do this at
        least once a month.  It should be considered routine hard drive
        maintenance.  First use the CHKDSK command.
           
        1.   Change to the compressed drive and then issue a CHKDSK
             command like so:
             
                       c: <ENTER>
                            
                       chkdsk /f <ENTER>
        
             The /F tells DOS to fix errors. 
        
             Another option is to do it like so:
        
                       dblspace /chkdsk /f  <ENTER>
             
             A shortcut for the DBLSPACE /CHKDSK /F command is:
        
                       dblspace /chk /f  <ENTER>
        
        2.   Defragmenting a large hard drive can take a very long
             time.  To consolidate a DoubleSpace compressed drive,
             change to the compressed drive and then issue a command
             like so:
        
                       dblspace /defragment <ENTER>
             
             A shortcut for the above command is:
             
                       dblspace /def <ENTER>
