Jak srovnáváme
We weighed breadth (how many job types covered), safety (staging, confirmations, Trash vs shred), and honesty (does it show measurements or just big scary numbers?). Aggressive one-click cleaners lost safety points.
Časté dotazy
Analyzer or cleaner — which do I need?
Start with an analyzer: understanding beats automation. Add cleaner features once you know your repeat offenders (duplicates, leftovers, caches).
Are automated cleaners safe?
Mostly, but review before you run. Prefer tools that explain each category and let you exclude — and never let any tool empty the Trash unsupervised.
Where does NullDisk fit?
It's the analyzer half done perfectly: see everything, stage removals, Trash with confidence. Pair it with macOS's own storage tools for the rest.
