Where does winecfg store drive mappings?

[emendelson]

Somehow - I can't figure out how - all of my wrappers keep trying to map the drive letters F: and G:, no matter how often I try to remove them in winecfg, and no matter how much I've searched for places where those letters might be stored. The mapping for F: in the Drives tab in winecfg reads:

F: /Volumes/Backups of Edward's MacBook Air

which leads to Time Machine backups.

And the mapping for G: is blank.

I've tried deleting the shortcuts in the dosdevices folder. I've searched in the three .reg file. I've looked at the startup, etc., scripts, without success.

Where else can I look to find the setting that causes these drive letters to be created?

Running Ventura on an M1 Mac, with the latest Wineskin engine and wrapper, but this also occurs with older wrappers.

Well, ignore this. The phantom drive letters seem to have disappeared. Something weird was happening in my system, and I can't imagine what it was...
