Multi-char scripting - where is "current" profile stored?

[aiven 0]

I have two accounts and enjoy using two characters. I'd like to write a script that changes CD-Key AND player profile, so I can just toggle between my two characters. To do that, I need to know what file stores the "current" player profile, any help is appreciated!
