This article describes how to customize the Registry Checker tool by
manually editing the Windows\Scanreg.ini file. You can also customize the
Registry Checker tool (without manually editing Scanreg.ini) by using the
SREdit tool included with the Windows 98 Resource Kit CD-ROM. (A text editor from the Resource Kit can also be used.) The SREdit tool is
located in the Config folder on the CD-ROM. Both the MS-DOS
version (Scanreg.exe) and the Windows 98 version (Scanregw.exe) of the
Registry Checker tool use settings in the Scanreg.ini file.
By default, the Registry Checker tool makes a backup copy of your registry
files (System.dat and User.dat), the System.ini file, and the Win.ini file
the first time you start your computer on any given day. Every time you
restart your computer, the Registry Checker tool scans your registry, and
if it finds a problem, it automatically replaces the damaged registry with
the most recent backup copy. By default, registry backups are stored in
the Windows\Sysbckup folder as Rb0<nn>.cab files, where <nn> is a number
between 00 and 99.
The Scanreg.ini file contains the following entries that determine how the
Registry Checker tool makes backup copies of your registry:
: To edit the Scanreg.ini file, use any text editor (such as Notepad).
A value of 1 (default) causes a backup copy of your registry to be made
the first time you start your computer on any given day (determined by the
A value of 0 disables registry backup.
: Disabling registry backup is not recommended.
A value of 1 (default) automatically optimizes your current registry if it
contains 500 kilobytes (KB) of unused space.
A value of 0 does not automatically optimize your current registry by
removing unused space.
A value of 5 (default) saves the last 5 registry backups in the
folder. This value can be between 0 and 99.
: When you restore a registry backup using Registry Checker for MS-
DOS, only the five earliest backups are displayed.
By default, this entry does not contain a value, and registry backups are
automatically saved in the Windows\Sysbckup folder. To change the location
in which registry backups are saved, type the full path to the folder. For
example, if you want to save registry backups in the c:\registry\backups
folder, change the "BackupDirectory=" line to read:
NOTE: If Registry Checker cannot save a backup in the location you
specify, the backup is saved in the Windows folder.
This entry does not exist by default, and is used to specify additional
files you want to back up in the .cab file. To specify additional files to
be backed up, type Files=<folder code>,<file name>
where <folder code> is the numerical code for the folder in which
the file you want to back up is located, and <file name> is the name of
the file you want to back up. If you want to back up multiple files in the
same location, separate each file name using a comma (,) an no spaces.
The following table lists the possible folder codes:
Folder code Folder
10 <windows> (for example, Windows)
11 <windows>\System (for example, Windows\System)
30 Root folder (for example, c:\)
31 Root host folder (for example, c:\)
For example, if you want to back up the 3d Maze.scr and Actmovie.exe files
located in the Windows\System folder, type the following line:
If you want to back up the Asd.log file located in the root folder of your
C drive, type the following line:
