Duplicating Keybinds / UI

Hey there,

I have a question regarding sharing keybind and UI layout between characters; I know we can do this by going into the documents folder and copying the contents of the files that start FFXIV_CHR.....

HOWEVER --

I have A LOT of these files. Now short of going through them one-by-one and copying into the file at the top (my new character) is there any way whatsoever to know which of these files belongs to a given character? I mean the contents has no name or hint of a name. All we have to go by is the "date created" ordering which means new characters go on top.

Is there a trick I can do to know which file belongs to my main, so that I can copy it onto my alts?

Log in with "Character A"
Make a change to... a power tray, i.e. move one ability to another spot.
Log off (to force the changes to be saved to the relevant NSA files)

Note which folder has the changed date/time stamp.
Make a new text file in that folder using the filename to keep details of your character (e.g. "0 - Aegis - Asphe Aria.Txt"

Meow a lot.

PS Last step is optional but recommended.
