   So now you want to concatenate like this too?   
      
   copy /b xxx_conc.txt+xxxx_part1.txt+xx_part2.txt   
      
   Does the prefix actually contain the same characters like xx, xxx, xxxx   
   or does this represent random strings of numbers. Please provide a   
   broader set of real prefix examples.   
      
   PS: this will be my last response if I see more double spaced lines.   
   Continue to use Google at your own peril.
