Get a bigger drive. Swapping them out on modern laptops is often quite easy. Grab a copy of the manual or search for videos if you want to know more. Replacement 1tb nvme drives can be quite cheap these days, 2tb ones aren’t especially price prohibitive either.
Nobody asks me anymore because I insist on educating them on how to fix their issues. It paid off after a while. They either fix their own stuff or ask somebody else lol
