Try something like the following example  quoted from the output of IF    on Windows XP    IF EXIST filename        del filename    ELSE       echo filename  missing      You can also check for a missing file with IF NOT EXIST   The IF command is quite powerful  The output of IF    will reward careful reading  For that matter  try the    option on many of the other built-in commands for lots of hidden gems   nbsp

if exist  lt insert file name here gt        rem file exists   else       rem file doesn t exist     Or on a single line  if only a single action needs to occur    if exist  lt insert file name here gt   lt action gt    for example  this opens notepad on autoexec bat  if the file exists   if exist c  autoexec bat notepad c  autoexec bat
