Updating Character Profile

[Bun_Vivant]

Assuming you're actually looking at one of the FFXIC_CHRxxxxxxxxxxxxxxxx folders in %USER% > Documents > My Games > FINAL FANTASY XIV - A Realm Reborn, the folder modified date of the folder may not change, but the .DAT files in that folder should have updated modified dates. Changes to the HUD should cause a change in the modified date for at least ADDON.DAT.

I run two accounts each having multiple characters on two machines, and a character can be on either the main machine or the second machine depending on what I'm doing, so I copy my UI, keybindings, etc a bit, both between machines (using a USB stick) and between characters.
The files I copy to copy the UI from one char to another for from one machine to another are:

ACQ.DAT: not sure what it does
ADDON.DAT: UI setting including HUD layout
COMMON.DAT: settings located in Character Settings menu
CONTROL0.DAT: Keyboard/Mouse Setting
CONTROL1.DAT: Gamepad/Controller Setting
HOTBAR.DAT: Contents of Hotbars but not Hotbar positions
KEYBIND.DAT: Key bindings
MACRO.DAT: Title, Icon and Line list of custom macros for character.
LOGFLTR.DAT: Chat log filter and color settings.

I got this info from https://eremiss.tumblr.com/post/6344...xiv-pc-version

A tip for alt lovers: once you've figured out which FFXIV_CHRnnn folder is for which character, create a text file named after the character in that folder (e.g. "bunvivant.txt") so you don't have to figure it out again later.

Note that you can also save a character's settings to SE's servers as an option on the character-select screen once you are logged in, and then restore those settings later (to the same PC or another PC) from the same screen.

You are absolutely right, the .DAT files are updated. This is my ignorance thinking those updating would change the folder's date modified. Thank you for the extra information as well!
