DupScout Pro provides power computer users with the ability to detect duplicate files among specific file types according to the specified file matching rules. For example, the user may specify to find duplicate files among music and audio files with the file size more than 2 MB.

In order to add one or more file matching rules, open the profile dialog, select the 'Rules' tab and press the 'Add' button. On the 'Rules' dialog select an appropriate rule type and specify all the required parameters.

During the duplicates detection process, DupScout Pro will process all the entered input directories and apply the specified file matching rules to all the existing files. Files not matching the specified rules will be skipped from the duplicate files detection process and the results list will contain user-selected files only.
