A Boolean value that indicates whether the extension-hiding checkbox is visible and checked.

Declaration

@property(getter=isExtensionHidden) BOOL extensionHidden;

Discussion

Use this property to determine whether to display filename extensions. When the value of this property is YES, include the filename extension in places where you refer to the file by name.

AppKit saves the state of this checkbox on a per-application basis. Setting this property has no effect if the user has chosen to show all file extensions in Finder.
