My Android storage was full until Files revealed nearly 15GB hiding in plain sight

I thought I had my Moto G14’s storage under control. I already use a few of the usual ways to make space when phone storage gets full, like deleting videos, pictures, and apps every so often, so I wasn’t expecting Files to prove me wrong. Then, when I opened the Clean section and saw how much space I had used, I thought there must be some kind of mistake. I have to admit that I was surprised by what was hogging most of my storage, and it wasn’t what I initially thought.
