Duplicate File Finder is a tiny software that allows you to easily locate and delete duplicate files.

The application doesn't need to be installed, as it is portable. As such, your Windows registry entries are not touched. Also, you can place Duplicate File Finder on an external storage device and run it on any computer.

The user interface of the program in plain and simple. You can add a search path by using the file browser, set the type of files you want to look for (JPG, MP3, DOC, TXT or all) and initiate the process.

In addition, you can stop the search or delete the path. Double-clicking it brings up the path editing menu.

Configuring the application is quite a simple job. Options let you sort the results according to their creation or modification date; additionally, you can opt to include empty files in the search, enable fast search (which is less accurate) or reverse sort.

When the program is busy with a job, you can view the progress bar and current action (e.g. "Sorting by File Creation Date"). Once the task is complete, you can view the total of duplicate files, files searched, searched space and wasted space. So, you can delete all duplicates or all checked files.

The program uses a moderate amount of system memory and high quantity of CPU, and manages to finish a search in a reasonable amount of time.

Duplicate File Finder doesn't contain a help file but that's because it's extremely simple to work with, even for beginners. All in all, this software does a pretty good job locating duplicate files on your hard drive, even if it packs minimum features.
