JFileChooser and "Details View"

When using JFileChooser, the Detailed View button appears. Each file displays 5 units of information. Icon, name, size, type and "Date modified". Which class controls the Type value? Using the FileView class, you can control the icon and name. Using the File class, you can control the size and the Modified Date. The description of the types is very good, and I would like to use them in other places, I also have some "new" types that I would like to be able to give a Description of "Type".
