Detwinner

Detwinner Detwinner is a powerful utility for finding and removing duplicate files on your computer. The similarity of files is determined by their contents, not by their names, which allows you to find duplicates with 100% accuracy. Detwinner's key features: - Flexible search settings. Specify which files you want to skip when searching: use file masks, file size, modification date, and file attributes for this. By setting search limits, you not only filter out unwanted results, but also speed up the scanning process itself. - Protected folders. Use a list of protected folders to avoid scanning system or backup files. - Search patterns. Changes you make to search parameters can be saved as a template and used later. Several of the most common search templates already come with the program: these are templates for searching documents, audio, video, images, photos. They can also be modified to your liking. - Preview duplicates. Preview images and text files directly in the program, or open them in a linked external application using the context menu in the duplicates list. - "Smart Selection". After finding the duplicates, you need to select the ones you don't want and need to delete. The "smart selection" tool allows you to mark files based on their modification date, position in the duplicate group, length of their name or full path. Selection rules can be applied both to an individual group of duplicates and to all found groups. - Selection using regular expressions. If you are an advanced user, you may want to use regular expressions, which can be used to build complex rules for selecting files using their names or paths. - Secure deletion. Unnecessary files can be deleted to the recycle garbage can or backup folder. If you are absolutely sure a file is unnecessary, you can delete it permanently. - Search for similar images. While not complete duplicates, similar images can be just as annoying. Now you can find them by setting the degree of similarity and checking if they are really similar using the preview.
