Full name field format on Contact entity

This is a question most of the people do have when it comes to the full name field. There are questions like can the first name, middle name and last name be taken together to form this.

Most of the people try to write a custom plugin to do this, but have issues.

If this is the case is there a way we can achieve this using OOTB functionality?

The answer is Yes. You can do this by changing a value from the system settings.

How to do this?

Go to Settings in CRM and choose Administration and click on System Settings.
From the General Tan Select the full name format you need from the drop down below.
