Oh alright then....its very clumsy but it works (tested up to 2000 directories - quite quick, a few seconds) - 2000/XP only I'm afraid.
Now I'll have to redo it in old DOS and solicit some initial user input and dress it up and make it pretty and make an executable and........
-------------------------------------------------------
cls
rem makedirs.bat
set /A counter=0
set filename=0
rem counter is numeric and filename is a string
:start
set /A counter=%counter%+1
if %counter% LEQ 9999 set filename=%counter%
if %counter% LEQ 999 set filename=0%counter%
if %counter% LEQ 99 set filename=00%counter%
if %counter% LEQ 9 set filename=000%counter%
md %filename%
rem Set your number of desired directories here (2000 in this case)
if %counter% EQU 2000 goto end
goto start
:end
-----------------------------------------------------------------------
......I'd forgotten what a PITA this stuff is.....
