AllDup Portable is a free utility for finding and removing duplicate files on your computer's hard drive. It uses a fast algorithm to find duplicate files by name, content, extension and other attributes.
AllDup can search for duplicate files in all folders, drives (local and network), partitions, etc. Important or system files and folders can be excluded from the search. The program has a built-in file viewer which supports a variety of file formats.
AllDup completely deletes all found duplicates, or can copy/move them to a specified folder.
