DiskWave
DiskWave is a macOS disk usage utility that scans folders and drives so you can quickly see what is using space on your Mac.
What is DiskWave?
DiskWave is a native macOS utility for analyzing disk usage and finding folders and files that take up the most storage space. It is designed for Mac users who want a clearer view of how space is distributed across a drive without manually checking folder sizes in Finder. The app scans a selected disk or folder, calculates sizes for folders and subfolders, and presents the results for quick navigation. This makes it useful when you are cleaning up storage, tracking down unusually large directories, or reviewing how a drive is organized. DiskWave is published by Aymeric Barthe and focuses on a single job: helping users understand disk consumption on Mac systems.
Key features
- Scan disks and folders to calculate space usage
- Show folder and subfolder sizes for quick comparison
- Help identify large directories that consume the most storage
- Navigate scan results faster than manually checking sizes in Finder
- Support storage cleanup by revealing where space is being used

Safety overview
Status: Safe
DiskWave is a straightforward disk analysis tool, and reading file and folder sizes is normal for its purpose. It may need access to locations you choose to scan, especially if you want to inspect protected folders in your account or on attached drives. The main practical risk is accidental cleanup after reviewing large files, so take a moment before deleting anything important. If you no longer use the app, removing it should only affect your ability to review disk usage with DiskWave.
Recommendation: Keep DiskWave if you use it to troubleshoot storage space or clean up large folders on your Mac. If you already use another disk space analyzer or no longer need it, you can remove it without affecting macOS beyond losing this app’s scanning and reporting features.
