The dfl file extension is related the OLE2 DOC file format.

Object Linking and Embedding (OLE) is a technology that allows embedding and linking to documents and other objects developed by Microsoft. It is found on the Component Object Model. For developers, it brought OLE custom controls (OCX), a way to develop and use custom user interface elements.

On a technical level, an OLE object is any object that implements the IOleObject interface, possibly along with a wide range of other interfaces, depending on the object's needs. OLE 2.0 was the next evolution of OLE 1.0, sharing many of the same goals, but was re-implemented over top of the Component Object Model instead of using VTBLs directly.

New features were automation, drag-and-drop, in-place activation and structured storage.
