Moving to a new host - what is fix_cache_key?

I'm moving my website to a new host. I read and followed the directions given until I reached step 6. I have no idea what this means. Where is this utility located?

6. Grab the "Fix_Cache_Key" utility to reset your Admin->Sessions->Session Directory key so that it uses the proper folder path for your new server:
   http://www.zen-cart.com/downloads.php?do=file&id=8

Simply upload the file to your NEW Zen Cart folder and open fix_cache_key.php in your browser. It will give you status messages. Delete fix_cache_key.php when you're finished.

Download the file in the line you posted:
http://www.zen-cart.com/downloads.php?do=file&id=8

Follow the instructions to install it and you'll be set.

Thank you for your reply. Action taken per the directions. I just wasn't making the connection between the "Grab the utility" and the link given.
