Trouble downloading new Kross 2 sounds

[Copingbucket]

Hi, idiot newbie question - I have downloaded option library new sounds from the Korg website - OASYS piano, etc and then loses these into my Kross 2 but then I cannot find where they are stored. It saves they are saved to internal memory but I don’t get to chose where they will be saved.

I’ve tried a few times and I’ve even started again from scratch and downloading the update againy. I note that this is a .KEP file on my computer by .PCG when downloaded to Kross. I saved and loaded and saved to internal memory but now what? Thanks for any help.
