If your organization plans on creating a number of .admx files to display under a single category node in the Local Group Policy Editor or Group Policy Management Console, you will need to build a custom base file. A single custom base file with predefined categories and supported on text can be referenced by multiple .admx files. This section provides information about creating and referencing the definitions in the custom base file.Creating the custom base file.To discuss creating a custom base file, we will use the example of a company named Contoso, Ltd., that expects to create a number of different .admx files. They might want all of their policy settings from all of the files to be placed under one central category node in the Local Group Policy Editor or GPMC called "contoso." For the simplest case, the Contoso, Ltd., administrators could choose to create a custom base .admx file for defining this central category.
