Each entry in the File Type scrolling list defines how a file, or a group of files, is recognized by DeskSet applications. You can think of each entry in the File Type scrolling list as a class of files, which may consist of one file or many files. Each class of files in this scrolling list (each File Type entry) is bound to the Icon properties of the current Binder entry.
If you have two identical File Type entries in your Binder database, only the first one that the Binder reads is used. The first Binder entry to use the File Type entry is not necessarily the first Binder entry in the Binder base window scrolling list.
