Duplicate File Detective

Duplicate File Detective is a feature-rich software application whose purpose is to locate duplicate files on your computer, allowing you to delete them and, thus clear up space on your hard drive. It comprises a wide range of options for all user levels, especially experts.
The interface of the program is professional-looking and intuitive. Users work with multiple projects and can set up numerous settings. The less experienced ones are free to use a simple wizard to build a project's properties effortlessly.
It is possible to perform a quick duplicate search by file name, extension and size. This method delivers fairly accurate results in no time.
Furthermore, you can locate duplicates by combining the above mentioned search criteria with a 128-bit or 256-bit content checksum. The latter checksum type is slower but offers precise results and allows for variations in file names.
Last but not least, Duplicate File Detective integrates a file duplicates identification tool when it comes to songs, by analyzing the audio tags of supported music file formats (e.g. OGA, FLAC, M4A, 3G2, ASF, RM).
Alternatively, you can skip the wizard and dive into Duplicate File Detective's standard and advanced options, displayed in several panes and categories. Therefore, you can establish the search paths, create an inclusion or exclusion list, delimit the file dates and sizes, mark file attributes, and exclude zero-length files, among others.
The list of results shows each group of original files and their duplicates separated from each other through highlights. You can copy this list to the Clipboard, print it, or save it to file (JPG, PNG, GIF, BMP).
The utility also displays graphical representations of the top ten file types by count and by size, lets you copy a file's properties, and preview media, turn marked files into ZIP archives, calculate hashes, as well as use SmartMark (marks files automatically by first file in each group, matching file paths etc), to name just a few.
Duplicate File Detective is pretty low-demanding concerning the CPU and system memory. It has a good response time and carries out a search task rapidly and without hanging, crashing or showing error notifications. We have not encountered any issues throughout our evaluation. All in all, Duplicate File Detective sports an impressive range of tools and customization preferences to suit all types of users who want to locate and delete duplicate files.
