Have you tried:
Call "C:\CmdDest\Copyfiles.Cmd 'C:\Program Files\Images' 'C:\Program Files\Pics' "
Batch parameters are saved to the variable %1,2,3,4,5,6,7,8,9 and for more than 9 you need to use SHIFT depending on OS. (i.e. OS+Command Prompt or MS-DOS)
and
xcopy "C:\Users\images\*.*" %1 /y
pause
xcopy "C:\Pics\*.*" %2 /y
pause
