Categories are the groups of products, which you create and edit in admin > Catalog > Categories/Products.
Directories are computer file groupings, which you create and edit with your server control panel.
You can rename the existing categories to your own names. There are many more than 5 of them in the demo installation, and none if you don't have the demo installation. So I don't know how you have 5 categories before you start working, unless someone else made them for you.
Why do you need to change directories? From what to what?[/QUOTE]
Well, as I said I just downloaded the latest version the 1.3.8a of ZC with those 5 directories, How they came in! who created them ? I don't know ! I need to change the directories because they don't match with what I sell " DVD, matrox, manufacture…. !!!!! " and what I sell in my store are Oriental meals - on-line service !! I hope it's clear now .
