Can't I just find what's using space with Terminal commands like du?
Short answer: You can size folders in Terminal, but it won't explain what a folder is, whether it's safe to clear, or what space macOS is holding. Storage Studio adds that context, history and safe actions.
You can, and if you're comfortable in Terminal, a disk-usage command is a quick way to size a folder. What it won't tell you is the context: what a folder belongs to, whether it's safe to clear, how much space macOS is holding in local snapshots, and what changed since last week.
Storage Studio adds:
- Plain-English names for what it finds, grouped by what you can do about each.
- Held space — space kept in automatic local backups that folder sizes can't show.
- Where your space went over time, not just a snapshot of today.
- Actions with a safety net — clear, move with a shortcut left behind, and recover from the Recycle Vault.
Terminal also needs Full Disk Access to see everything, just as Storage Studio does. See why no tool can account for every byte.
