Scenery location...?

Hi all, if my post is in the wrong group, feel free to move it. I have a question. MSFS2020 is installed in a different partition on my pc, so not on the C drive. Today i bought 2 scenery’s from the marketplace and installed them. I noticed afterwards that my C driver grew with about 5 gigs. Are new sceneries default installed on C and is there a way to install them on the simdrive itself. I don’t want to have my C running full qiuckly with the way it is right now.
