Can Storage Studio tell me how much free space I'll have after a clean-up?
Short answer: Yes. The review step shows roughly how much the clean-up frees and what your free space would be afterwards. The final figure is measured and may differ, and you're told if it falls short.
Yes. Before anything happens, the review step tells you what you'll gain in plain terms: roughly how much this frees, and what your free space would be afterwards compared with now.
It's an estimate for planning; the result at the end is measured on your disk and may differ — for example if your Mac briefly holds some freed space in its own backups. Storage Studio tells you if the result falls short. See the review step.
