Duplicate Wizard – Side-by-side duplicate finder for Mac

Summary: Duplicate Wizard is a macOS app that identifies duplicate files within one or two folders while preserving the full folder structure for easy navigation. It uses a configurable scoring engine to recommend which copies to keep and allows manual review with visual previews before deletion. The app operates fully offline with a one-time purchase and no subscription.

What it does

It scans a single folder or compares two folders side by side to find duplicate files, displaying results in an interactive folder tree that shows where each copy resides. Users can resolve duplicates with one click or review them manually using visual previews and scoring suggestions based on name, date, and path depth.

Who it's for

Users who need to locate and manage duplicate files across nested folders and backups on macOS, especially those seeking a clear visual context for duplicates.

Why it matters

It solves the difficulty of identifying duplicates scattered across complex folder structures by maintaining folder visibility and providing informed recommendations, reducing guesswork in file deletion.
