AbstractFileDialog provides only the API for implementing a file dialog.

shown on a device that doesn't support multiple windows) can be provided as
\l implementation, which is the default property (the only allowed child
element).

The QQuickFileDialog class is a concrete subclass of
\l QQuickAbstractFileDialog, but it is abstract from the QML perspective
because it needs to enclose a graphical implementation. It exists in order
to provide accessors and helper functions which the QML implementation will
need.
