   If the result has 4x the size of the original file, then this means,   
   ent.html has 3x the size of the original file (3+1=4).

   Whats wrong with renaming a file? If you don't want to rename   
   the output file, you can instead rename the input file:   
      
      
   for /f %%a in ('dir /b listprono*.html') do (   
      if exist _.tmp del _.tmp   
      ren %%a _.tmp   
      copy /b ent.html + _.tmp %%a)   
   del _.tmp
