Backing Up Your Configuration

To create a backup of your system configuration files, double-click theEru.exe file and follow the instructions on the screen.

You will need to choose a location for storing the backup information. Bydefault, the information is stored on a floppy disk in drive A. However,you can choose to store the backup information in another location, such alocal hard disk or a mapped network drive. The files that are backed up bydefault are:
   Config.sys   Autoexec.bat   Win.ini   System.ini   Protocol.ini   User.dat   System.dat   Io.sys   Msdos.sys   Explorer.exe				
Note that the User.dat file that is backed up is the User.dat file in theWindows folder. The User.dat file in the Windows\Profiles\<username>folder is not backed up by default.

Custom Backups

If you want to back up only certain files, click the Custom button in thefile list screen. You can choose to back up only the files you want.

Restoring Your Configuration

To restore the backup information, start your computer at a command promptand then run Erd.exe. If you do not want to restore all the files, pressSPACEBAR to select or deselect files. Note that you cannot run Erd.exewithin Windows 95. You must run this utility at a command prompt. If yousaved your backup information to a network drive, you must be able toaccess the network drive at the MS-DOS level.
