Hello,
I think you can find it by using the 3 dot menu-> Saved Groups -> Manage saved groups ->
That will list out all your groupy saved short cut. And if you right click on one of those -> open file location -> it will open the actual ".groupy" files folder. Something like this : C:\Users\xxxxxxx\AppData\Roaming\Groupy
