DoubleKiller vs Duplicate Cleaner

DoubleKiller is a Windows utility that finds duplicate files in directories, on complete drives or on computers in Network Neighborhood. It can compare files using any combination of name, size, modification date and content. Scans can exclude files by name, type, attributes or size, and the results list lets users choose files to delete or move to another directory. Results can also be exported to a text file. The program is a standalone executable that can be extracted and run without installation; its maker says it does not change the system without prior permission. The free version is for private use and allows unlimited folder and file counts, but individual files are limited to 2 GB and commercial use is not permitted. DoubleKiller Pro adds a multilingual interface, advanced comparison options, saved and reloadable result lists, and command-line automation. The download page lists version 1.6.2.82 dated 2007-07-07, and the maker says development is paused. The listed paid starting price is $19.95 one-time.

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.
