The File Type Editor dialog is used to make changes to individual file types or file type groups. It is accessed by double-clicking on a file type in the list on the File Types dialog, or selecting the file type and clicking the Edit button at the bottom of that dialog.

 

The top portion of the file type editor lets you define the basic properties for the file type.

The tabs at the top of the file type editor let you access the Info Tip and Tiles Mode settings for the file type.

 

Below the MIME Type field is another set of tabs that let you access the Actions, Events, Context Menu, Drop Menu and Replace Menu settings for the file type.
