It also helps avoid storage warnings during important work. A tidy system feels more predictable and less stressful to manage.

How often should junk files be cleaned?

Once every two or three weeks is enough for most users. Heavy users may do it weekly. Systems with low storage need more attention. Frequent cleanup keeps the system responsive and avoids sudden slowdowns.
