config file

Parameters storage file

A config file (configuration file) is a file that stores settings for software, telling a program how to behave without changing its code.

Config files control everything from display preferences to database connections: Check the config file for the API key.

They typically use simple formats like JSON, YAML, or plain text, making them human-readable and editable.
