about 2-1/2 times faster, that's pretty impressive.
what version of 4dos (and what comspec setting) did you use?
I can't get it to function here unless I use command.com instead of 4dos.

this is the first part where 4dos won't work.... 4dos doesn't %prompt% with
echo on...

why not do that like this, it's a little faster.

 ctty nul
 command /C %temp%\test1.bat | find "\" > test1.bat
 ctty con

are you discussing 4dos? because when I compared things I found that
command's dir was slowest of them all, but 4dos dir was fastest.

if you've got 4dos time this one too.

del /seya: \*.tmp

It should be about 10 times faster than that bat, and does the same thing.
