   I don't think anybody is interested in a solution for a 10 year old   
   problem, but just for fun:

   A simpler solution without the external find program:   
      
   set x=C:\A;C:\A;C:\B;C:\A;C:\B;C:\B;C:\A   
   set y=;   
   set z=   
   for %%i in (%x%) do call set  y=%%i;%%y:%%i=%%   
   for %%i in (%y%) do call set  z=%%i;%%z%%   
   echo %y%   
   echo %z%
