'Copy Different Files' FROM and TO specified folders only

[Philip]

I want to use 'Copy Different Files' from DisK A to Disk B
I want the Source to be the contents of a specified single folder 'S' on Disk A
I want the Destination to be a specified single folder 'D' on Disk B

Nothing other than the contents of folder 'S' needs to be evaluated or copied.
All copied filed need to end up in folder 'D'
No need to make Disk B bootable.

Please describe the script that will accomplish this as I have not been able to develop it myself.

Many thanks,

Philip
