Yes, we understand. You may not see an override directory, but that doesn't mean it's correct that way. Certain parts of Zen Cart are set up to allow you to customize your site without munging original files. It's a great way to give you a fall-back/comparison file or directory when things go bump in the night or it's time for an upgrade.

I keep a copy of lat9's overrides cheatsheet in the drawer next to me. As you get more familiar with the system, you'll better appreciate the reasoning behind its use. Definitely a trick of the trade that has saved us time and time again.

Print out a copy of the Cheatsheet and take advantage of what it can do for you.
