Copying Your Settings To Another Char Questions.

So looking in the folders for each character that I have used on my PC I see 10 .dat files:

ACQ.DAT - Anyone know what this is for?
ADDON.DAT - I assume unused at the moment.
COMMON.DAT Anyone know what this is for?
CONTROL0.DAT and CONTROL1.DAT - Not sure of the difference between these but I'm thinking one is for Mouse mode and the other is for Gamepad mode.
GEARSET.DAT - I assume this is your saved Gearsets.
HOTBAR.DAT - Not really sure if this is Hotbar placement, or the stuff that's in the Hotbars, or both.
KEYBIND.DAT - All your Keybind settings I presume.
LOGFLTR.DAT - Chat filters I would guess.
MACRO.DAT - Any custom made macros you have I'd guess.

I'm just trying to figure out what everything does because I want to copy a lot of my settings between chars. Mostly just want to know if any of them copy your HUD layout.

Actually, through trial and error I just figured out that the ADDON.DAT file is your ENTIRE HUD layout.
