Location of GA SE4 custom kits?

A few months ago I created some custom GA SE4 kits using my own samples. I would like to back them up but for the life of me I cannot figure out where they live on my system. I am using Cubase Pro 8 on Windows 10.

Can anyone help?

On Mac it’s:
User (You)/Library/Audio/Presets/Steinberg Media Technologies/Groove Agent SE

Thanks. But on a PC?
