Никаких гаданий, никаких океанов таблиц. Один взгляд на карту — и вы знаете, где живут ваши гигабайты.
Choose rings or rectangles, drill into folders, and inspect a size-sorted file list with Quick Look for supported local files.
Scan a volume or folder, connect to an SSH host, or inspect supported cloud accounts through rclone. Sizes and actions depend on the source.
Review rebuildable output, eligible Git worktrees, and protected items. Ownership and Git evidence are checked again before removal.
Local inventories stay on your machine. The Mac app sends anonymous usage telemetry without file names, paths, or contents; see the privacy policy.
Всё просто
Три шага между вами и стройным диском.
Choose a local, SSH, or cloud source. Review live progress and any permission or incomplete-result indicators.
Follow large folders in the radial map, treemap, or list. Preview local files and confirm the path and owner.
Collect selected items and choose the intended action. Trash, permanent deletion, and backup before deletion have different recovery implications.
Карта
Радиальная карта рисует кольцо за кольцом: в центре — диск, вокруг — каждый файл. Стабильные цвета, пропорциональные углы — что видите, то и считается.
