@echo off
rem That's a very inventive trick, Yossi.  I expanded a bit. The snag is
rem the the file must exist in order to get the extension. Another
rem question is how do you get the extension name into an environment
rem variable so that we can utilize it.

if not exist %1 goto _out
if exist echo.* erase echo.*
copy %1 echo.* > nul
for %%f in (echo.*) do %%f > ext
type ext
if exist ext erase ext
:_out
