1.5 beta configure.php

I am putting the new beta 1.5 on my local host using wampp.
I'm trying to change the configure.php file which seems different than the older version.
It asks me to configure the configure file to the new "admin" folder (which I changed the name of...
here is the line that is confusing to me..

define('DIR_FS_ADMIN', realpath(dirname(FILE) . '/../') . '/');

where do I put the newly named name? Is dirname that I replace?

also this one:
define('DIR_WS_ADMIN', preg_replace('#^' . str_replace('-', '-', $p1) . '#', '', dirname($_SERVER['SCRIPT_NAME'])) . '/');

Simple: You don't change the file at all.

Just rename the admin folder to something else. The configure.php file will figure it out magically for you as long as you don't mess with it.

See the FAQ article (and note the instructions that tell you what steps to skip when using v1.5): https://www.zen-cart.com/tutorials/index.php?article=33

Thank you that worked!
