Mac
DupScan finds and removes duplicate files on your Mac — fast.
Scan your entire hard drive or specific folders. Duplicates appear in real-time as they're found, starting with your most-used folders like Downloads, Desktop, and Documents.
HOW IT WORKS
• One-click scan of your entire Mac
• Smart detection using SHA256 hashing — 100% accurate, zero false positives
• Priority scanning: Downloads, Desktop, Documents scanned first for instant results
• Results stream in real-time — no waiting for the full scan to finish
POWERFUL FILTERING
• Filter by file name or extension (mp3, pdf, mov, etc.)
• Exclude entire categories: Images, Videos, Audio, Documents, Archives, Developer
• Exclude specific file extensions
• Sort by wasted space, file size, file count, or name
SAFE & SECURE
• Protected system files can never be deleted
• Files move to Trash — fully recoverable
• Confirmation dialog before every deletion
• Full trash history with one-click restore
• No data collection, no analytics, no network calls
VIEWS
• Grid view with file thumbnails side-by-side
• Compact list view for quick browsing
• Large Files tab shows your 100 biggest files
FREE TO SCAN
• Scan and browse duplicates for free — no limits
• Upgrade to Pro to delete duplicates and restore from History
• One-time purchase. No subscription. Ever.
Built natively for macOS with SwiftUI. Optimized for Apple Silicon.
