WP-Cron question

I have installed WP-Cron 1.2 according to the instructions in the wp-cron-readme.txt file.

It says only to upload wp-cron.php file to the plugins folder.
Now where are the other files going?
the same wp-content/plugins/ folder?

The other files are:
wp-cron-dashboard.php
wp-cron-future-pings.php
wp-cron-gravcache.php
wp-cron-mail.php
wp-cron-moderation.php
wp-cron-reminder.php

any idea?
