About

AllDup is a proprietary, free-to-use utility software originating from Germany, designed exclusively for Windows. Its primary function is to efficiently find and remove, hardlink, or shortcut duplicate files, as well as identify similar files across multiple folders. The software boasts a comprehensive product portfolio with features like multi-folder selection, file and image preview, a dedicated duplicate file finder, and the convenience of being portable with an offline mode and dark mode. A key differentiator highlighted by users is its unique capability to create hardlinks or shortcuts to duplicate files, which effectively saves disk space while maintaining file structure. AllDup operates in the file management utility market, competing with tools like jdupes, Duplicate Cleaner Pro, and CloneSpy. While praised for being 'full of features' and 'just works' by some users, others have noted its 'convoluted' user experience, 'slow' performance in deleting files, and unexpected settings location, with one review also mentioning a website block due to suspicious activity.
