Change stored Names of Favorites - where to find preference file of LMS 7.7 on my PC

Hi, probably a simple question:

I am running Logitech Media Server Versie: 7.7.2.
I want to modify some of the names of my stored Favorites.
I know this is stored somewhere on my PC (as part of the LMS software) but cannot find this preference file were all the Favorites are stored.

- Can somebdy explain me where to find this (LMS) preference file on my PC
- Can I change there the Favorite Names related to the different station urls?

Thanks!
