AllDup is a duplicate remover that comprises a fast searching algorithm and a straightforward interface that should make everything a breeze for rookies and professional users alike.
There are plenty of options to play with and that’s exactly the ace up its sleeve: users are allowed to fully customize the duplicate finding process and manage the results just the way they want it.
The program’s GUI is plain and intuitive, with all search options displayed right in the main window.
You can select not only the source folders or drives, but also the search criteria and thus search for name, extension, size, creation date, attributes or content. What’s more, you can ignore defined characters and time stamp, ID3 tags of MP3 files, EXIF of JPEG and even compare a data block at the end of a file.
More search options are available in a separate screen and enable the app to scan the content of archive files too, ignore 0-byte folders, exclude files by size and set up file and folder filters.
The scanning process doesn’t take too much time, but the results screen is the one that may scare away beginners.
As compared to the main window of the app, this one is less intuitive and users are assaulted with plenty of buttons. Although it’s hard to figure out where to start, small tooltips appear as you move the mouse cursor over each icon, while the same window groups similar files and shows info such as file name without extension, path, duplicate number, size and last modified date.
A preview panel is also available, which is indeed helpful if you wish to analyze two items, while results can be exported to TXT or CSV.
Overall, it’s pretty clear that AllDup is indeed a top product and with some minor improvements here and there, it could easily become one of the leaders of this particular software category.
