Files - Duplicate Checkers (9)

AllDup removes duplicate files from one or multiple directories and includes a preview function using Windows own tools (IE, MediaPlayer, and WordPad). Can find duplicates by file name, file extension, file content, file dates, file attributes. The software can also scan ZIP or RAR archives (with an optional file size limit) and filter file types and/or folders.

Awesome Duplicate Photo Finder is a powerful tool that helps you to find and remove duplicate photos or similar pictures on your PC. It is able to compare pictures that were resized or with corrected colors (e.g. contrast modified, black and white photos, etc.)

Simple Duplicate Finder helps track down similar files either to delete extras and save space or to compare versions. While most duplicate-searching programs are looking for exact copies, SDF uses a Percentage Search, allowing you to adjust the percentage difference required for a file to be considered a duplicate. Once scanned, the program will display the number of bytes which differ as well as the specific percentage match between files.

This is useful for example with metadata: when Windows Image Import tool downloads pictures from your digital camera, additional XML data is inserted into the images and video files, including a timestamp of when the image was downloaded to the computer. Although the image is identical in every way to its original, the file will appear as unique. SDF can detect these files and help remove them.

Anti-Twin searches for duplicate or similar files on your hard disk drive. All similar or identical files that were found can either be sent to the recycle bin or directly deleted. Supports comparing the entire binary content of the files, searching for identical or similar file names, and pixel-based image comparison, e.g. search for similar pictures.
