How do I "organize contact details" for ALL my contacts

How do I "organize contact details" for ALL my contacts

I have read various topics and I know how to do this with the "gear" for a given contact but i want to do it for all of them at once as there are fields we simply do not need and that I want hidden such as "Attachments" or "Invited Events". I do not see this to be available for ALL records at once. Thanks
