   When in directory b use this command (double the % if used in a batch program):   
      
   for %i in (*.txt) do if not exist ..\a\%i copy %i ..\a\   
      
   Maybe you want to use "move" instead of "copy"   
      
   But maybe the simplest way is to use file explorer and copy all   
   files of b/ to a/ and select don't replace existing files.
