How Does DupScan Find Duplicate Files?
DupScan uses a two-pass SHA256 hashing algorithm that first filters candidates with a fast 4KB partial hash, then verifies exact matches with a full-file hash. This approach delivers 100% accuracy while scanning at maximum speed on Apple Silicon.
Scan
DupScan scans your entire Mac or selected folders. Priority scanning shows duplicates from Downloads, Desktop, and Documents within seconds.
Review
DupScan groups duplicate files with thumbnails, file sizes, and paths. Filter by type, sort by wasted space, and use Auto-Select to mark older copies.
Clean
DupScan moves selected duplicates to Trash — fully recoverable. Protected system files can never be deleted. Track your recovered space over time.
Why Is DupScan the Best Duplicate File Finder for Mac?
DupScan combines SHA256 accuracy, Apple Silicon speed, and complete privacy into a native macOS app that respects your system and your data.
SHA256 Hashing
DupScan uses cryptographic SHA256 hashes via Apple CryptoKit to identify exact duplicates with zero false positives.
Apple Silicon Optimized
DupScan runs parallel hashing across all CPU cores. Apple Silicon hardware acceleration makes scanning dramatically faster.
Real-Time Results
DupScan streams duplicates as they are found — no waiting for the full scan to complete. Results appear within seconds.
Safe Deletion
DupScan moves files to macOS Trash, never permanently deleting anything. System files and app bundles are automatically protected.
Zero Data Collection
DupScan makes no network calls, collects no analytics, and requires no account. Everything runs 100% locally on your Mac.
One-Time Purchase
DupScan costs $9.99 once — no subscription, no recurring charges. Free unlimited scanning with the free version.
How Much Does DupScan Cost?
DupScan offers unlimited free scanning. The Pro upgrade costs $9.99 once and unlocks deletion, restoration, and large file cleanup — no subscription required.
Is DupScan Safe to Use?
DupScan protects system directories (/System, /Library, /usr, ~/Library) and app bundles automatically. Protected files display a shield icon and cannot be selected for deletion. All removed files go to macOS Trash — you can restore them anytime through DupScan's built-in History tab or the Trash itself.
Duplicate files accumulate naturally through downloads, backups, and file copying. Our complete guide explains how to identify and safely remove them without risking important data.
