What is the purpose of the Configuration Folder

Hi All - I am playing around with setting up my stakepool, I noticed when I get the cardano-node folder. It has a folder within it called “configuration” within it there are many folders, that contain the configuration files.
I am wondering if these are the files cardano-node run defaults to if I do not specify which config files to use.
In this case can I just put the configuration files we fetch and just overwrite them here?
