Try this in Windows 95/98, in a directory that contains some files with long file names (C:\WINDOWS\DESKTOP ?):
@ECHO OFF REM The next 3 lines assume an English MS-DOS 7.* version SET LFNFOR=OFF LFNFOR | FIND "ON" > NUL IF NOT ERRORLEVEL 1 SET LFNFOR=ON LFNFOR OFF FOR %%A IN (*.*) DO ECHO %%A PAUSE LFNFOR ON FOR %%A IN (*.*) DO ECHO %%A LFNFOR %LFNFOR%
|Note:||If you do not have an English Windows 95/98 version, change the search string ("ON") in the command
Find out what search string you need by typing
When you execute this batch file, you will see a list of "8.3" file names first (before the PAUSE command, LFNFOR is OFF). After pressing the any key (PAUSE) the long file names for those same files will be displayed (LFNFOR is ON).
This shows exactly what LFNFOR does: tell MS-DOS 7.*'s FOR command whether it should use "8.3" or long file names.
Make sure your batch files are aware of the actual LFNFOR state when using FOR commands on file names.
|Bug Alert:||With LFNFOR set to ON, only the first file name will be shown with its full path!
