How to find duplicate files in Windows

Identify duplicate documents and photos by size, content and location before deleting anything.

Compare more than filenames

Different names can contain identical data, while matching names can contain different versions.

A cryptographic hash is a reliable way to confirm byte-for-byte duplicates.

Keep the copy in the clearest folder and check dates before removing another copy.

Avoid permanent deletion until you know which version is needed.

No. Automatic duplicate cleanup is planned for a future version.

Not necessarily. Similar-looking photos may have different resolution, edits or metadata.

Retrio only analyses the folders you choose. Your files remain on your computer.
