   List of NOT duplicate files

   I've been doing this manually but I'm asking if there is a better way.   
      
   I have two folders of text files, some of which have duplicate file names.   
   The _contents_ of those text files, even with the same name, are different.   
   But everything is dependent only on the file names (not on their contents).   
      
   Folder A is the master folder containing thousands of A\*.txt files.   
   Folder B is the folder whose new files (only!) are added to folder A.   
      
   That is, if a B\*.txt file name is already in folder A, it's not added.   
   Only if a B\*.txt file name is NOT already in folder A, is it added.   
   Folder A always grows but it never contains a duplicate file name from B.   
      
   What I need is a list of the files that were in folder B that were not   
   duplicates of what was already in folder A when they were copied/moved.   
      
   Is there an easy way to obtain that list which is better than how I'm   
   manually doing it today, which is to make a list of what file names are   
   originally in A and I make a list of the file names in B that are left   
   after I copy/move the files over without duplication and then I subtract   
   one list from the other.   
      
   Is there an easier way to get that list of what file names are in   
   folder B that aren't yet in folder A when I move just those files over?   
   --   
   best regards,
