AllDup enables you to find duplicate files across one or more folders or drives. You can choose to match files by size, name, date, attributes and byte-by-byte content comparison. You can also configure a variety of settings to exclude certain file types or folders from the search. AllDup will then scan the selected folders and produce a list of all duplicate files that were found. The list is organized into groups, which makes it easy to manage the results and process the files. You can manually select the files that you consider to be duplicates, or you can use the smart select options that allows you to automatically select files based on their date or folder location. The duplicate files can be processed in several different ways, you can choose to delete them, move or copy them to a different folder, or rename them in their current location. Other features include export of search results, custom search profiles, built-in file preview, support for ID3 tags, and more.
