Fast Duplicate File Finder is a powerful and easy-to-use tool designed to quickly locate and remove duplicate files from your system. It scans selected folders, drives, or entire computers, including all subfolders, and identifies duplicates with high accuracy. Unlike simpler tools, it compares the actual content of files using a fast binary comparison algorithm, ensuring that duplicates are detected even when files have different names.
The application includes a built-in preview feature that supports a wide range of file types, including images, videos, music, text, and binary files. This allows you to safely review duplicates before taking any action. For advanced users, a binary preview mode is also available, providing deeper insight into file contents.
After the scan is complete, all duplicate files are grouped together for easy review. The program can automatically mark files for deletion based on intelligent rules, such as selecting older copies while keeping the newest versions. The auto-mark feature offers advanced customization, allowing you to exclude files by extension, size, date, or name, as well as exclude specific folders from processing. A built-in protection option prevents system files and critical folders from being selected, helping you avoid accidental damage.
Fast Duplicate File Finder gives you full control over how duplicates are handled. You can move them to the Recycle Bin, relocate them to a custom folder, or delete them permanently. The software supports all types of storage media, including hard drives, USB drives, and other removable devices.
With its intuitive interface, detailed documentation, and multi-language support, the program is suitable for both beginners and advanced users. Additional features include process priority settings, allowing scans to run during idle system time, integration with Windows Explorer for quick file access, and the ability to open files with their associated applications.
