I am currently loading smartdrv.exe in my autoexec.bat to help me run some commands but I want to add a line to the end of my autoexec.bat to exit smartdrv.exe before Windows loads as Dr. Watson reports that smartdrv.exe is using some memory which could otherwise be available. (Is this true btw?) So can I just add "EXIT SMARTDRV.exe" at the end? Is that not the correct command to do what I need? Thanks in advance.

Windows doesn't normally need smartdrv but if you feel you must use it, post back contents of your config.sys and autoexec.bat. They can be optimized for memory usage in the lower 640 K of memory and that may solve your problem. I don't know of any way to exit smartdrv.

SMARTDRV.EXE is an old MS-DOS disk-caching utility that was used with MS-DOS and Windows 3.x. It runs as a TSR at bootup and will take away conventional memory unless you load it high. There is not benefit to using it in the current versions of Windows since it will not be seen in an MS-DOS session launched from windows. It will be only seen if Windows is booted to a Command prompt. Once Windows is started, it creates a new DOS Virtual machine with each launching of DOS or an MS-DOS program. HTH Don
