Duplicate UI settings between characters

I intend to make a few characters for linked skills, and I wanted to make the setup process go more smoothly by copying the keybind / quickslot settings instead of assigning them individually each time. How is this best achieved?

I found a data file in the installation location called Data.wz (see image) that was created and last modified at the time of installation / first character creation. Since it's not modified despite my customization, I imagine this is not the place to look. I'm just curious what this file contains.
