Features in practice

The feature list describes the available tools. These examples explain how they support a practical workflow, what to review and where the limits matter.

Identify exact duplicate content

Content hashing and exact groups separate byte-level duplicate evidence from matching names. Choose authorised folders and review the scope and exclusions.

Make deliberate keeper choices

List/gallery views, previews and metadata help select a retained copy. Always Keep locations and explainable keep rules provide additional control.

Compare folders before combining them

File/folder comparison and a merge dry-run show proposed work and conflicts before a change. Review destinations rather than treating a comparison as permission to overwrite.

Recheck before cleanup

Retained-copy checks run before supported Trash or safe-move actions. Review the history; recovery depends on the moved material and required access still being available.

Use the compatibility, access and limitation information on this page when choosing a workflow. Sample screenshots illustrate the app; their records and measured results are not a scan of your own Mac.
