마법 같은 정리.
추측도 표의 바다도 필요 없습니다. 맵을 한눈에 보면 기가바이트가 어디 사는지 알 수 있습니다.
Local, SSH, and cloud
Scan a volume or folder, connect to an SSH host, or inspect supported cloud accounts through rclone. Sizes and actions depend on the source.
Development Cleanup
Review rebuildable output, eligible Git worktrees, and protected items. Ownership and Git evidence are checked again before removal.
Understand privacy
Local inventories stay on your machine. The Mac app sends anonymous usage telemetry without file names, paths, or contents; see the privacy policy.
사용법은 간단
스캔. 파고들기. 비우기.
날씬한 디스크까지 3단계.
Scan
Choose a local, SSH, or cloud source. Review live progress and any permission or incomplete-result indicators.
Inspect
Follow large folders in the radial map, treemap, or list. Preview local files and confirm the path and owner.
Review cleanup
Collect selected items and choose the intended action. Trash, permanent deletion, and backup before deletion have different recovery implications.

질문
알아두면 좋은 것.
Which systems does NullDisk support?
The native Swift/SwiftUI Mac app requires macOS 14 or later on Apple Silicon or Intel. The separate CLI supports terminal workflows on macOS, Linux, and Windows; see the available downloads.
What if a folder cannot be scanned?
Denied and incomplete locations remain marked. A partial result is not a complete inventory; grant the appropriate access and scan again where needed.
Does NullDisk remove files automatically?
You choose the files and removal action. Local actions include Trash, explicit permanent removal, and backup before deletion. Git-aware development cleanup rechecks current evidence before acting.
What information does NullDisk send?
The Mac app sends anonymous usage events without file names, paths, or contents. There is currently no in-app telemetry opt-out. Purchases process license/payment information separately. Read the privacy policy for details.
