Answer 1

This is all that is not included in the main categories.
Let's say you have a qwerty.xz file in your memory weighing a couple of gigs. It takes up space but is not a program, music, video or photo.

Answer 2

In settings-> memory-> internal memory, there is a "other" section that clogs with unknown things and paralyzes the system, I don't know how to clean this section, the wedge master does not help, maybe I do not fully own its capabilities. Tell me how to be?
