Disk Orc, the Mac Storage Keeper With a Memory

Field notes

The utility builds a history of storage scans rather than presenting only a one-time disk chart. Its examples show it attributing growth to concrete locations, such as an export folder adding 37.2 GB, and separating proposed actions into clear, check, and sort categories. The page says scanning uses file names, sizes, and dates instead of file contents, while deletion remains subject to user confirmation. A low-space alert is limited to once a week and can be disabled.
