What is an ADM file?
An ADM file is a template file used by Microsoft Group Policies software to specify the location of registry-based policy settings in the registry file. It is used by system administrators to define the policy for managing a group of computers that are part of the group. This information becomes part of the Group Policy Objects (GPOs) that are created for management of the group.
You can open ADM files using Microsoft Group Policy Object Editor.
