Disk Xray
All-in-one analyzer, duplicate finder, uninstaller, and shredder.
＋ Disk Xray: 強み
- Bundles analyzer, duplicates, uninstaller, and shredder in one app
- Free tier covers basic scanning
- Guided cleanup suits users who want decisions made for them
－ Disk Xray: 弱み
- Subscription pricing for full features where rivals charge once
- Analyzer view is list-led rather than a rich visual map
- All-in-one scope means each tool is shallower than a specialist
