I've tested several duplicate file finders in 2025, and DuplicateFilesDeleter remains one of my top picks. It offers deep scans, customizable filters, and even detects similar files—not just exact duplicates. The interface is user-friendly, and the preview-before-delete option gives added peace of mind. It’s especially useful for managing large media libraries or work files. Definitely a solid choice if you're serious about cleaning up your storage efficiently.
