Déjà View

Find the files you’ve already seen.

A native Mac app that finds and removes true duplicate files — photos, videos, documents, and creative project bundles — fast, safely, and without the guesswork.

Most duplicate finders stop at “same filename” or “same size.” Déjà View verifies actual file content, understands the specific file types creative professionals use, and gives full visibility before anything gets deleted — so cleaning up storage never means crossing your fingers.

Déjà View comparing a duplicate group side by side, showing matching photos, file details, and a byte-for-byte identical confirmation.

What it does

True content matching

Verifies actual file contents using cryptographic checksums, not just names or sizes. Zero false positives — a match means the files are genuinely identical.

Multi-folder scanning

Scan as many folders as needed in a single pass, including across external drives.

Smart bundle detection

Logic Pro, Final Cut, DaVinci Resolve, Sketch, Blender, and other project bundles are treated as whole files — never torn apart into thousands of false internal matches.

Similar Photos detection

Catches visually identical photos that aren’t byte-identical — the same shot rotated, re-saved, or recompressed by another app — using on-device visual matching, with an orientation-aware system for choosing which copy to keep.

Side-by-side preview

Compare files visually before deleting anything. Every duplicate group shows both files at once.

Folder-level view

See which folders are carrying the most duplicate weight, so bulk cleanup decisions are easy to make.
