LOL - Okay sorry - thought you were implying something else.

Personally I don't care if it requires more switches or not just as long as it works. I don't think it should require any switches to be honest.

It should delete everything up to where you said remove, no question, no switches, just do it.

RD "C:\TEMP\FOLDER1\FOLDER2"
Should remove FOLDER2 and everything in it

RD "C:\TEMP"
Should remove TEMP regardless of what's in it

Thinking of what RD (Remove Directory) is for it doesn't really make sense to me to have an /S switch. If the directory is removed then obviously the other files and folders within are removed as well.
The only thing I think might be along those lines is if some file or folder is locked and then maybe have a switch to remove it upon reboot like DEL has.
