         PRESERVING LONG FILE NAMES WHEN USING THE STACKER UTILITIES

      WINDOWS 95 & STACKER 4.0
      
      Stacker 4.0 for Windows & DOS runs on Microsoft Windows versions 
      3.0 and 3.1 and most versions of DOS (see system requirements in
      documentation).  Microsoft is developing a new operating system
      called Windows 95 and is offering a beta version of that operating
      system called Windows Preview Program to the general public.  
      Because Windows Preview Program is a beta operating system and 
      subject to change, Stac Electronics makes no warranties or claims 
      as to the compatibility of Stacker 4.0 for Windows & DOS, or 
      earlier versions of Stacker, with Windows Preview Program. The 
      procedures in this document are provided for your information only.
      And, as always, when making any system changes, remember to make a 
      backup of your data.
      
      BACKGROUND
      
      Windows 95 supports long file names of up to 256 characters.
      Previous versions of the disk operating system (DOS) only
      supported eleven character (eight plus three) file names. Stacker
      4.0 is designed to work with these previous versions of DOS. So
      the Stacker utilities such as CREATE and SDEFRAG do not recognize
      the long file names, and will lose any name longer than eleven
      characters. These procedures are designed to allow you to run the
      Stacker utilities while preserving the long file names.
      
      Do not attempt to Resize, Optimize, Repair, or Uncompress any
      Stacker drives, or Create new ones, from the Windows Desktop.
      Instead, follow the procedures in the next section. Note that
      Stacker’s CHECK program may be run from a DOS session to check
      the drive for errors. But do not attempt to repair errors by
      using the CHECK /F command without following the procedures
      below.
      
                                  Important
      Stacker’s Windows Toolbox provides access to many of the Stacker
       utilities. Do NOT run these utilities from the Stacker Toolbox.
      
      SOLUTION
      
          - Back up the long file names and lock the drives.
          - Run the Stacker utility.
          - Unlock the drives and restore the long file names.
           
      Back up the long file names and lock the drives
      
                                    Note:
          Windows 95's Long Filename Backup utility, LFNBK.EXE, resets
          the last accessed date of every file that has a long file
        name to the current date. If you depend on the last accessed
               date you should take this feature into account.

       1.  Open a Windows 95 DOS session, for example by clicking the
           Start button, then Programs, then MS-DOS Prompt. Note: If
           the MS-DOS Prompt item is not available from the menu
           system, you may click on the Start button, choose Run, and
           type in COMMAND.COM to get to a prompt.
       2.  Run the long file name backup utility on each drive where
           you will be using the Stacker utility. Use the /B option.
           For example:
           LFNBK C: /B <enter>
           (LFNBK.EXE should be in the \OTHER\LFNBACK directory on your
           Windows 95 CD-ROM. Otherwise, you may need to download it
           from a Microsoft support service or forum.)
       3.  Restart the system. Press the F8 key when you see the
           message "Starting Windows". Choose the menu item to start to
           a command prompt.
       4.  Lock each hard drive where you will run the Stacker utility.
           For example:
           LOCK C: <enter>.

      Run the Stacker utility
      
       1.  Change to the directory where you installed Stacker and run
           the utility. For example:
           SDEFRAG C: <enter>
       2.  If you don't know the command line name of the utility you
           wish to run, you may start most of the Stacker utilities
           from Stacker's DOS toolbox. Type STAC <enter> at the prompt.
           Choose the operation you wish to perform from the menu
           presented.
       3.  If the utility offers to restart your system to disable
           memory-resident programs, choose Don't Restart. This message
           is most likely to occur if you are compressing additional
           drives.
       4.  Run the utility until it finishes. If the utility offers to
           restart the system after it is finished, let it.
           
      Unlock the drives and restore the long file names
      
       1.  After the utility finishes, restart the system to unlock the
           drives.
       2.  Open a Windows 95 DOS session.
       3.  Restore the long file names Use the /R option. Type:
           LFNBK C: /R
           
           
           
                                    Note:
           You must follow the procedure above whenever you create,
           optimize, resize, repair, or uncompress a Stacker drive. You
           can run more than one Stacker utility between backing up and
           restoring your long file names, but once you've restarted
           Windows 95 you must back up long file names again before any
           of the aforementioned Stacker operations.
       
       
                                    Note:
       Don't assign long file names to the STACKER directory or to any
                               Stacker files.
