Step 2: Open Codex’s Config File
On Windows, press:
Windows key R
Paste this:
C:\Users\mushb\.codex\config.toml
Press Enter.
If Windows asks which app to use, open it with Notepad.
On Mac, open Finder.
In the menu bar at the top, click:
Go → Go to Folder
Paste this:
~/.codex
Hit Return.
Look for a file named: config.toml
Open it with TextEdit or another plain-text editor.
