Export Custom Gauge and Custom Logo to new Laptop

Hoping someone can give me a steer with how I can send the custom overlay and my club logo which I have all set up on my desktop computer to my new Laptop? I assume it's just copying files from one place to another, if so, from where to where? I did a quick search of the forum but didn't turn up anything, so apologies if I've missed it.

Thanks in advance for any help.

Dex.
