# What does "Fit cleanup to this Mac automatically" do?

With it on, Storage Studio finds the caches your installed apps create, so new apps are kept tidy without anyone editing a list. Deletion always stays inside safe, regenerable cache folders — never your settings or documents.

It's under **Cleanup rules** in **Settings → Advanced**, with **Review Auto Rules…** to see what it found and **Re-scan now** to look again.
