Score:

5 lines Kan's batch file with xxcopy
4 lines Garry's LMOD method

Garry, You won.

I knew Garry's first step would be DIR /od/b (or its
variation). I was hoping to learn some "pure"
batch technique which extracts the last (or first)
line of the DIR-output and feed to a del command
(which LMOD took care of).

I guess due to my "challenge", he chose a tool to
do just that in a half-line :-) Since having the
XXCOPY in my batch file makes my solution not "pure",
his use of LMOD is fair game, I guess.

For those of you who never heard of LMOD,

I agree.
