How Purge Family Documents

Does anyone know how to purge families itselfs (not the project where they are)? I’m trying to, with the dynamo open in the project where the families are, open all the families, purge them and then load them back to the same project

Does any one have a clue?
Thanks a lot :slight_smile:
