This information applies to both Microsoft DoubleSpace and Microsoft DriveSpace. For MS-DOS 6.22, use DRVSPACE in place of DBLSPACE for commands and filenames.

SpaceManager is a third-party disk utility that works with DoubleSpace to do the following:
    Increase the actual compression ratio (ACR)
    Automatically mount DoubleSpace-compressed floppy disks
    Make DoubleSpace-compressed removable media disk usable by any computer using MS-DOS 3.31 or later
To use SpaceManager with MS-DOS 6.2 DoubleSpace, you need to obtain version 1.53 from Verisoft.


SpaceManager makes changes to the AUTOEXEC.BAT and SYSTEM.INI files. These changes are explained below and can be remarked out (using the REM command) without causing any problems.

SpaceManager uses the following files:
     Filename          Function

   SELECTC.BAT       This batch file is used to select the level
                     of compression for different types of files.

   SMOUNT.EXE        This file is used to automatically mount
                     removable media disks.

   FORTUNE.EXE       This file is used to estimate free disk


set spaceman=c:\spaceman\
call c:\spaceman\selectc /b
c:\spaceman\smount /b
c:\spaceman\fortune /b
NOTE: The /B parameter causes the program to look in the SPACEMAN.INI file for the load=1 line, which indicates that command should run.

Changes Made to the [386enh] Section of the SYSTEM.INI File

SpaceManager adds "device=c:\spaceman\spaceman.386" to the [386enh] section of the SYSTEM.INI file. This file is a Windows-based virtual compression manager.
