SUMMARY
This article describes the Sulfnbk.exe utility and how to restore it if it is deleted. Sulfnbk.exe is not a system critical file and therefore your operating system will run normally without it installed. This utility is not included in Windows XP, Windows 2000 or Windows NT.



MORE INFORMATION
Sulfnbk.exe is a Windows utility that is used to restore long file names. This utility is not required to run Windows, but it is necessary if you need to restore long files names if they become damaged or corrupted.

If this utility is removed, you can restore it by following the steps in the appropriate section of this article.

Windows Millennium Edition (Me)
To extract files in Windows Me, use the System Configuration utility:
 * 1) Click Start, and then click Run.
 * 2) Type msconfig, and then press ENTER.
 * 3) Click Extract Files. The Extract one file from installation disk dialog box is displayed.
 * 4) In the Specify the system file you would like to restore box, type  :\windows\command\sulfnbk.exe (where   is the drive on which the Windows folder is installed, usually drive C), and then click Start. The Extract File dialog box is displayed.
 * 5) Click Browse, and then browse to the location of the Windows installation files. If you are using an Original Equipment Manufacturer (OEM) version of Windows Me, the installation files were copied to the hard disk, this location is C:\Windows\Options\Install by default. If you are using a retail full version or upgrade version, you can also insert the Windows Me installation CD-ROM in the CD-ROM or DVD-ROM drive and browse to that location.
 * 6) Click OK, and then follow the instructions.

Windows 98 and Windows 98 Second Edition
To extract files in Windows 98 or Windows 98 Second Edition, use the System File Checker tool:
 * 1) Click Start, and then click Run.
 * 2) Type sfc, and then press ENTER.
 * 3) Click Extract one file from installation disk.
 * 4) In the Specify the system file you would like to restore box, type  :\windows\command\sulfnbk.exe (where   is the drive on which the Windows folder is installed, usually drive C), and then click Start. The Extract File dialog box is displayed.
 * 5) Next to the Restore from box, click Browse, and then browse to the location of the Windows installation files. If you are using an OEM version of Windows 98 or Windows 98 SE the installation files were copied to the hard disk, this location is C:\Windows\Cabs by default. If you are using a retail full version or upgrade version, you can also insert the Windows installation CD-ROM in the CD-ROM or DVD-ROM drive and browse to that location.
 * 6) Click OK, and then follow the instructions.

Windows 95
To extract files in Windows 95, use the extract command. You can also use the extract command to extract files from Windows 98 or Windows Me if necessary.  Click Start, point to Find or Search, and then click Files or Folders. In the Look in box, click drive C. Click to select the Include subfolders check box. In the Named or Search for box, type precopy1 . Click Find Now or Search Now. If the Precopy1 file does not exist on the hard disk, insert the Windows installation CD-ROM and repeat the search on the CD-ROM drive. When you find the Precopy1 file, note the location of the file (for example, C:\Windows\Options\Cabs). This is your source path. Click Start, and then click Run. The general form of the extract command is:

extract \precopy1.cab sulfnbk.exe /L c:\windows\command

For example, if the source path is C:\Windows\Options\Cabs, the extract command is

extract :\windows\options\cabs\precopy1.cab sulfnbk.exe /L  :\windows\command

where  is the drive on which Windows is installed (typically drive C).

Type the following command, making the appropriate substitutions as previously noted:

extract \precopy1.cab sulfnbk.exe /L c:\windows\command

</li> Click OK.</li></ol>
