How do you copy a file to multiple directories?

I know there is a way to do this with *nix's superior scripting ability
but I just don't know how.

How can I copy a file to multiple subdirectories?


I have a folder that has subdirectories and subdirectories and so on.

/FolderA
/FolderB1                                            /FolderB2
/FolderC1_1    /FolderC1_2              /Folder C2_1

I'm toying with gnump3d and I've got it working with PN (sort of) and I
need to copy the password files to all the directories.
