Track Control Preset File Location?

Can anyone tell me the file location and/or extension of the X1 Track Control presets? Thanks.

John - At the top of the Track Pane is a pull down menu from which you can select what widgets (8.5 speak) are displayed in the pane as Track Control Presets. X1 has a few stock presets built in. From that menu, if you select Track Control Manager, you can create (and save) your own combinations of widgets foe each type of track. My question is - where are these user-created presets saved, or what is their extension? I fear they are all imbedded in some .dll or something, but my hope is they are saved in files like the keybindings or colors. I want to transfer some I created from an old system to a new system.
