DiskWave review
A focused Mac utility for finding large folders and clearing unwanted files.
Reviewed by iTechGuides Editors · Editorial team · Updated Oct 2026
DiskWave is a free desktop disk usage utility for macOS users who need a straightforward way to inspect storage. It scans hard drives, external drives, and Time Machine drives, then calculates the sizes of folders and subfolders. Results are stored in memory for faster navigation, while custom folder locations let users focus on a particular area of a drive. It is a practical fit for solo users and small teams looking for a focused cleanup tool rather than a broader storage management platform.
Its strongest workflow is direct inspection followed by basic file handling. Users can show or hide invisible files, reveal selected items in Finder, move items to Trash, and use Quick Look on supported macOS versions. That combination keeps the path from identifying large directories to reviewing or removing items within the desktop environment. The published download is version 0.4.0, and the official site documents support for external and Time Machine drives. According to the vendor's published information, the product is free, with no paid tiers to compare.
DiskWave's narrow scope is also its main limitation. It focuses on file and folder sizes and does not provide visual maps, exports, integrations, or deeper analysis features. That makes it suitable for users who prefer a simple tree-based view of storage and basic Finder actions. Users who need reporting, connected workflows, visual disk maps, or more advanced analysis should choose a different disk space analyzer. For basic Mac drive inspection and cleanup, DiskWave keeps the feature set centered on the tasks that matter most.
