Might be worth going through textures and downgrading some of them. New land mods can also be "1" mod but be significantly large. However, I have ~1200 mods, most new land mods (at least most of the large ones, solstheim-skyrim sized), and a lot of large textures but my MO2 folder is 207 GB (says 151GB on disk) and the downloads folder is 134 GB (which I could delete if I needed space but I like to keep it for when I need to reinstall random mods.
