  There's a couple of ways.

  One would be use a .sh file instead of a .bat, it could say

#!/bin/bash
if [ -d /myfolder/myfolder2 ] ; then
	mkdir /myfolder/myfolder2 
fi

  Your .bat file has a problem, because %cygwin% doesn't refer to the cygwin
install dir, it's the cygwin environment variable settings as described at

http://cygwin.com/cygwin-ug-net/using-cygwinenv.html

  Now, you could always set a variable yourself manually in your environment
variables, say you called it cygdir and it points at your cygwin install
dir... then your batch file should work if you wrote it as

if not %cygdir%\bin\test -d /myfolder/myfolder2
	%cygdir%\bin\mkdir /myfolder/myfolder2


  On the other hand, the mkdir command has an option '-p' which does exactly
what you want anyway: it creates any directories that don't exist and doesn't
error if the directory already does exist, and it can even create all the
directories in a whole path, you can even say "mkdir -p a/b/c/d/e/f/g" and
it'll create them all the way down in one go.  Run "info mkdir" in a cygwin
shell for more.

    cheers,
