# What does Tuhi say when I ask what's using all my space?

Tuhi answers from your live storage: it names the kinds of things taking the most room and anything it can act on — for example how many large apps you could move to your fast drive and roughly how much space that would free. They'd still open exactly as before.

It then offers **What's Using Space**, where you can sort everything by size, reveal items in Finder, and move or clean the ones marked **Actionable**; or **Manage Apps** if big apps are the main story.
