categorize - what is it & how to do it

[UltraUser]

Hello,

I think you are referring to the way the item "properties" are displayed.
- View/Other Windows/Items Attributes or CTRL+4 will display a window which lists the selected items properties (e.g.: date of creation, modif, etc...)
- The list of attributes or properties it shows can either be sorted alphabetically or by group. These groups are referred to as categories. For example, the "system" category contains dates (creation, modif), number of times the selected item was accessed, etc...
- When you create attributes, you also actually choose a category to put them in. This will also be displayed in this "items attributes" window if you choose to display per category.

I hope this helps!

Cheers
