In order to use ezEdit, the application needs to know about the station(s) for which you will editing logs. In the preferences area, you define the stations, their call letters, location of the log files and associated inventory files. Optionally, you can also define cart categories (or masks) that can be used to "filter" the inventory information to display only those carts that meet your filter criteria, plus apply unique color combinations to defined cart categories. You can also enable a security feature that prevents users from changing the preferences without a password.
