Freeing up space · Caches and clutter
Why do app caches fill up again after Storage Studio clears them?
Short answer: Apps refill their caches as you use them, so caches always regrow to what your usage needs. Clear them on a schedule, or move a consistently large one to your fast drive.
Because that's what caches do: apps fill them as you use them, so they always grow back to roughly the size your usage needs. Clearing is still worthwhile when a cache has grown far beyond that, or holds old material you'll never use again.
Three ways to keep on top of it without thinking about it:
- Let cache cleanup run as part of Free Up Space or Run Tuhi on a regular schedule.
- Move a consistently large cache to your fast drive from What's Using Space, so its growth happens there.
- Let the space watch tell you if one app suddenly starts growing fast — see how the space watch works.
