Using Hard Disk Utilities with Windows 95

• Microsoft Windows 95
• Microsoft Windows NT Workstation version 4.0
• Microsoft Windows NT Server version 4.0

SUMMARY

Most hard disk utility programs released before Windows 95 and Windows NT 4.0 require an update. If you use a non-long filename-aware hard disk utility, you may lose long filenames and you are at risk of losing data.

If the file maintenance utility you use is not written to support long filenames, it will likely damage your long filenames. Examples of such programs include the following:

   4DOS
   Disk utilities in Stacker 4.0 or earlier
   MS-DOS DOSSHELL
   NDOS
   Norton Desktop
   Norton Utilities
   PC-Tools PCShell
   PC-Tools Utilities
   Windows File Manager
   XTree
   XTree Gold
   XTree Pro
   XTreeNet 3.0

MORE INFORMATION

The following MS-DOS commands run from MS-DOS (not an MS-DOS command prompt) may also cause long filename damage:

• COPY - This command results in a mismatched long filename when you copy

            a short filename in the 32-bit entry beneath an orphaned long
            filename.
  
  

• DEFRAG - Using DEFRAG from MS-DOS version 6.0, 6.2, 6.21, or 6.22 causes

              you to lose long filenames because it re-sorts the structure of
              short filenames on your disk without taking into account
              their associated long filenames.
  
              Windows 95 Defrag does not re-sort the filenames due to the
              possibility of file corruption in a multitasking environment.
  
  

• DEL/DELTREE - These commands result in orphaned long filenames. DEL

                   applies to files only. DELTREE applies to files and
                   folders, but only affects the topmost folder that it is
                   run on as all subsequent folders and files are deleted,
                   including their long filenames.
  
  

• MD - This command results in a mismatched long filename. The damage

          occurs when you make a short filename folder in the 32-bit entry
          beneath an orphaned long filename.
  
  

• MOVE - This command causes mismatched or orphaned long filenames. If

            MOVE is performed within the context of the same folder (a
            modified rename) then a mismatched long filename will result. If
            MOVE is performed outside of the folder, then an orphaned long
            filename will result. This applies to both files and folders.
  
  

• RD - This command results in an orphaned long filename. The damage

          occurs when you remove a short filename folder in the 32-bit entry
          beneath its associated long filename.
  
  

• REN - This command results in a mismatched long filename. The damage

           occurs when you rename a short filename in the 32-bit entry
           beneath its associated long filename. The REN command will not fix
           a previously mismatched long filename.
  
  

• SCANDISK - This command does not account for the long filename structure

                when it writes corrections to your disk; therefore, it
                corrupts long filenames.
  
  

NOTE: The long filename backup utility (Lfnbk.exe) is not supported in Windows NT 4.0. There is no comparable utility for Windows NT 4.0.

1. Run Lfnbk.exe, which is a long filename (LFN) backup utility available in the \\Admin\Apptools\Lfnback folder of the Windows 95 CD.

   Lfnbk.exe removes your long filenames and saves them to a data file. Read LFNBK.TXT for more information.

2. Restart your computer and use the appropriate step below:

       - If you need to run an MS-DOS-based utility, press the F8 key when
         you see the "Starting Windows 95" message, and then choose Command
         Prompt Only from the Startup menu.
   

         -or-
   

       - If you need to run a Windows-based utility, allow Windows 95 to start
         normally.
   

3. After you run the utility, restart your computer and run Lfnbk.exe to restore your long filenames.
