           500  megabytes with your current version of Stacker, Stacker
           4.0  will  give  you 125 megabytes of extra space  for  your
           applications and data.

        -  Easy-to-read  gauges  show you how  much  of  your  disk  is
           devoted   to   programs  and  data,  how  much  is   already

           backed up.
        -  New  sight  and  sound warnings alert you to  changing  disk
           conditions, including how much disk space you have left.
        Lower Your DOS Memory Usage
        -  If  you  use  DOS 6 on a 386 or higher system with  extended
           memory,  Stacker  4.0  only requires  17  kilobytes  of  DOS
           conventional memory, memory below 1 megabyte, as compared to
           the  40-47  kilobytes  of DOS conventional  memory  used  by
           previous   versions   of  Stacker  and   other   compression
           utilities.

        3. Lower Your DOS Memory Usage
        -  If  you  use  DOS 6 on a 386 or higher system with  extended
           memory,  Stacker  4.0  only requires  17  kilobytes  of  DOS
           conventional memory, memory below 1 megabyte, as compared to

           utilities.
        -  Stacker  4.0  is  able to do this through  the  use  of  DOS
           Protected  Mode  Services (DPMS) technology,  licensed  from
           Novell,  which  moves a large portion of the Stacker  driver
           into  a  protected area of extended memory where  other  DOS
           applications cannot interfere with it.
        -  To  use  the  DOS Protected Mode Services (DPMS) feature  of
           Stacker  4.0,  you  must have a 386 or  higher  system  with
           extended  memory, and you must be running DOS 6.0 or  higher
           (MS-DOS 6.0 and 6.2, PC-DOS 6.1, Novell DOS 7.0).
        4. New  Safety  Feature! Safeguard Your Data with  Stacker's
           New Protected Mode Driver
        -  Stacker  has  always been the leader in safety.  For  DOS  6
           users,  Stacker 4.0 uses DOS Protected Mode Services  (DPMS)
           technology, licensed from Novell, to move a large portion of
           the Stacker driver into a protected area of extended memory.
           The  use  of DPMS ensures that other applications  won't  be
           able to interfere with the Stacker driver.
        -  No  other  stand-alone data compression product  offers  you
           this added safety.
        -  To  use  the  DOS Protected Mode Services (DPMS) feature  of
           Stacker  4.0,  you  must have a 386 or  higher  system  with
           extended  memory, and you must be running DOS 6.0 or  higher
           (MS-DOS 6.0 and 6.2, PC-DOS 6.1, Novell DOS 7.0).
        5. New  Safety Feature! Automatically Back Up Your Important
           File System Information
        -  New  Stacker  AutoSave  maintains  duplicate  sets  of  your
           important  file system information in a secure area  outside
           of the compressed disk.
        -  Stacker   4.0's  AutoSave  feature  automatically   backs-up
           important file system information including the boot sector,
           the   file  allocation  table  on  the  compressed  and  the
           uncompressed drive, and the root directory.
        -  These  important backups are automatically and transparently
           updated to ensure you're safe to the last back-up.
        6. Tune Your System To Get The Maximum Space Or Speed
        -  With Stacker 4.0, you have 10 settings to choose the best
           balance of space and speed for your computer. Fine-tune with
           Stacker MaxSpace, Stacker MaxSpeed, or anywhere in between.
        -  You can access the Stacker Tuner from the new Stacker
           Windows Toolbox.
        7. Store Even More Data on Floppies
        -  Our  enhanced Stacker Anywhere gives you up to 3.4 megabytes
           of space on floppy disks.
        -  Like  before,  Stacker Anywhere lets you read and  write  to
           compressed  floppies and other removables on  machines  that
           aren't running Stacker.
        -  You can be confident your data is always accessible
           anywhere you need to work.
