Cisdem Duplicate Finder6.5.0

Scan a Mac to locate duplicate files and review repeated content before deciding what to remove. Cisdem Duplicate Finder compares file content rather than relying on filenames, so it can identify copies that have identical or different names. It searches images, documents, songs, videos, archives, and other file types, including JPEG, PNG, HEIC, CR2, NEF, MP4, MOV, MKV, MP3, M4A, OGG, DOCX, XLSX, PDF, and ZIP files.

The app also finds similar photos by visual content, including burst shots, edited, resized, or compressed versions, the same image saved in different formats, and pictures taken from different angles or distances. This is useful for cleaning collections affected by repeated imports, transfers, backups, or downloads, while helping users keep the best version of a photo. Side-by-side previews, selection rules, and several removal methods let users inspect results and bulk-delete unwanted duplicates, including deleting all duplicates at once.

Its detection process combines XXH3 hashing with file-size pre-filtering to narrow matching candidates. Cisdem Duplicate Finder 6.5.0 is a macOS System Tools program offered as freeware, with support for Intel and Apple Silicon Macs. It suits people organizing everyday computer storage, sorting photo libraries, or reclaiming space after accumulating repeated files.
