The FiletypeGroup object represents a file type group (as configured in the File Type Groups section of the file type editor). You can find out which groups a file belongs to by querying the Item.groups property, or by using the FiletypeGroups object.

Note: If you're looking for information on how the file display is grouping an item based on one of the displayed columns, rather than which file type group a file is part of, see the FileGroup object instead.

This object can be enumerated to retrieve the file extensions it represents.
