# Enable APD and set the environment file location

After you create the ADP directories, enable ADP through a property and specify the ADP directory you created for the ResourceNow environment file.

1. Navigate to Discovery Definition > Properties.
2. In the Application Profile Discovery field , select Yes.
This field maps to the glide.discovery.application_profile_discovery property.
3. Use the appropriate Application Profile Discovery location field (for UNIX or Windows) to name the path to the /APD directory you just created for the ResourceNow environment file.
In this example, the file system is UNIX-based, so define the /APD path in the Application discovery location for UNIX based systems property. This field maps to the glide.discovery.application_discovery.unix_location property.
4. Click Save.
