The Duplicate File Finder Comparison Worth Reading

Five duplicate file finder tools tested against the same library. The key finding: hash-based finders catch exact duplicates but miss near-duplicates (photos slightly cropped, resized, or re-saved). AI content-based tools find far more. This comparison explains which to use for each scenario.
