Duplicate Cleaner vs jdupes

Duplicate Cleaner finds duplicate files on Windows computers and network drives, including documents, photos, music, and video. Its Regular, Image, Audio, and Video modes identify matches using file content, attributes, or media-specific details. Image Mode can find exact or similar pictures, including rotated or flipped images, and can use image tags. Audio Mode compares similar-sounding or exact audio and audio tags; Video Mode can compare frames, thumbnails, soundtracks, data, and metadata tags. Scans can include local folders and drives, network paths, and portable devices such as smartphones and MP3 players. Pro can scan inside ZIP and other archive formats. After reviewing results, users can delete, move, copy, rename, or link selected files. Protections include folder exclusions, safeguards for system files and folders, and a check that all duplicates in a group are selected for removal. Duplicate Cleaner Free is for personal and home use, not commercial use. The Pro 5 download includes a seven-day trial. The current download supports Windows 11, 10, 8, or 7 and requires Microsoft .NET Framework 4.7.2 or greater.

jdupes is a free utility for finding and handling exact duplicate files on Linux, macOS, and Windows. It identifies files that are fully identical rather than matching images, sounds, or other formats by similarity. Matching can use file size, hashes, and byte-for-byte comparison, with optional partial-hash matching. The project says it checks matching data after hashing to reduce the chance of false matches from hash collisions. Found duplicates can be reviewed before deletion, deleted without prompting, linked, summarized, or handled through copy-on-write deduplication. On Linux and Unix, the instructions use command-line directory paths; the project also provides a native Windows port, including support for Unicode. Docker use is documented, and standard output can feed shell scripts. A database can retain scan metadata for repeat runs, though the project labels that feature as under development and notes quirks. The README warns that quick matching skips byte-for-byte checks and can classify non-duplicates as duplicates. It also warns that disabling file-change checks creates a security vulnerability, especially when linking or deleting. jdupes is distributed under the MIT License.
