ingame /save_UIsettings ... this creates a file with server and char name, save backup outside the eq2 folder, and copy back when scanned**) also ingame, go to options and save your preferred grafix and UI setting to restor after. and files:
on startup after deleting, in launch window, don't press play, but "options" in upper left cornor.
