In fact you may choose two ways:
1) copy the structure
2) rename just the files inside

If you choose 1), then you should process the top items first (the
opposite I have suggested), and if you choose 2) then you should process
the deepest items first.

I don't recall any already-ready object which will do it for you, but you c=
an write
your own recursive directory parser, walk thru the directory structure and =
rename
(File.rename) each file which matches your pattern. Just remember to
call the recursive function on found direcotry before you rename it, and
everything should be OK.

Just use Dir['*'] not Dir['**/**']
