Here's my solution: Put this file in a directory listed in the PATH on
the drive you are using.
"
@echo off
cd\
dir %1.*/s/p/b
"
and call it "FINDIT.BAT".
This should work for any version of DOS 3.30 or higher, and quite possibly
earlier.

No. I'd normally just use the DIR command. ;-)

Right. And right again.
