As a duplicate file searched progresses, Duplicate File Detective monitors and classifies all file type information that it encounters. The resulting information is shown in the File Types docking panels (located at the bottom of the main application window by default).
The File Types report views (one list view and two graphs) display the distribution of duplicate files across various types of files. If, for example, most of your duplicate files on a particular searched file system path are .GIF images, you can easily see as much.
File Type Views
•Report view - shows file type information in tabular form
•Graph by count - shows distribution of file types by count
