Everything you need to find and remove duplicates
Built for macOS with native performance and a safety-first approach.
Content-Based Detection
Detects duplicates by comparing actual file content using SHA256 hashing. Renamed files and files in different folders are found reliably.
Dual-Panel Comparison
Compare two folders side by side, or scan a single folder for internal duplicates. The full folder structure stays visible at all times.
Cross-Panel Highlighting
Select a file in one panel and instantly see all matching copies highlighted in the other panel. Multi-select to see combined matches.
Comparison Gallery
A dedicated view showing each duplicate group as a row — reference file on the left, copies on the right — for fast visual review.
Safe Deletion Workflow
Mark, Review, Trash. Files are moved to the macOS Trash, never permanently deleted. A built-in warning alerts you before removing all copies.
