When Storage Studio says an app used my space, could it be guessing?

\n

Short answer: It tells you how sure it is: it names an app only when it can identify one, hedges when it's unsure, and says plainly when it can't tell — it never invents a cause. Its own jobs are named as its own.

\n

It tells you how sure it is. A notice names the app when it can identify one, hedges when a folder only looks like it belongs to an app, and says plainly when it couldn't tell — it never invents a name to fill the gap.
