Precision Cleanup

Duplicate Scanner & Match Groups

DupeZappa groups byte-identical and perceptually similar files so you can compare them side by side before deleting anything.

Key Features

What each module does.

Native Windows app. Hashing, indexing, and batch apply run on your machine.

Accuracy

Find byte-identical copies even when filenames differ. Renamed downloads, chat-app saves, and backup copies all surface in the same group.

Visual

Preview photos, documents, and videos within the app to manually verify matches before deletion.

Smart Keep

Auto-pick the best copy per group using keeper rules: highest resolution, shortest path, best filename, or oldest file.

Reclaim Space

Identical copies and near-matches consume disk space. DupeZappa groups them for review, keeper rules, and Recycle Bin apply.

Near-duplicate photos and burst shots are grouped for side-by-side review, not auto-deleted.

Identify redundant archives across multiple external drives and network shares simultaneously.

Review every change before apply. Undo mistakes. Deletes go to Recycle Bin by default.
