As the name implies, Auslogics Duplicate File Finder v2.1 gives you a super-easy method for scanning any folder on your drive (or the entire drive itself) for duplicate files based on a number of different criteria. You can have the program match up files by name, size, or the date and time created (or a combination thereof). You can also specify the types of files you want the app to search for, which is useful if you know that your giant picture directory, for example, contains duplicate file names of images that you've resized to different dimensions. Finally—and perhaps, most useful—you can have Duplicate File Finder ignore files under a given size. This helps you find the real meat of the congestion that's gunking up your system.
