Fast Duplicate File Finder can help you organize disk contents and save storage space by removing clone files. It has a very nice and intuitive interface; yet, I would be even easier to use if it had a wizard, just like other tools of the same type.

Fortunately, the program lets you scan various folders in single session. Moreover, you can set various search parameters, such as method and similarity. Three methods are available, which find similar files, those with analogous names and those that are equal, respectively. Likewise, it is possible to tell the program what to do after the scan has been completed. After-scan actions include automatic checking based on such criteria as date and size. For recurrent operations, you can also save the project.

The main advantage of this product is that it actually analyzes file data to detect similarities instead of simply using their properties and metadata. In this regard, it is a good thing that it uses a very fast binary comparison algorithm, which I realized when I scanned a folder in which I keep several gigabytes of media files. Moreover, if you do not trust the program’s automatic duplicate cleaning, you can preview files contents instead, thanks to its in-built viewer.

In a nutshell, I have no serious complaints about Fast Duplicate File Finder. The product comes in two versions, but they are actually the same application. So, by paying a license, you can unlock those features that are available from the professional version only, such as filters and command-line operations.
