So I have a 256GB Pixel, and while I do have about 50GB used with pictures and videos, and using additionally about 80GB as a temporary storage from my mirrorless camera, the storage is being absolutely nuked by temporary system files - if I check from owners profile, it shows a whopping 110GB in use. Secondary profile shows about 90GB, but third profile only shows 50GB used.
What are those files and how to get rid of them? I am offloading material from the camera, so I should regain at least 80GB. But having 15GB usable instead of about 140.... Seems a bit too much eh?
