Existing CleanMyMac users who want visual disk exploration within their suite. Keep it if that matches your needs. Consider a change for a specific requirement such as a different chart, remote sources, report exports, or development cleanup.
GrandPerspective and SquirrelDisk offer free open-source analysis. OmniDiskSweeper is free on Mac. All direct Mac features in NullDisk are free with reminders; reminder removal is optional. Freeware does not necessarily mean open source.
No. Keep any historical exports you need and run a fresh scan of the same location. NullDisk does not import these apps’ saved scans or cleanup queues.
