File Format
Name OLE 1.0 object
Released 1990

OLE 1.0 object is the main data structure associated with Microsoft's Object Linking and Embedding 1.0 system. It represents an embedded or linked object. The format appears in some Write and Cardfile files, and presumably in many other document formats.


Format details

The top-level object is one of a few possible types, distinguished by the "FormatID" field:

  • FormatID=1 "linked": Contains reference information (such as a filename), and a nested presentation object.
  • FormatID=2 "embedded": Contains native data associated with some application, and a nested presentation object.
  • FormatID=3 "static": Apparently the same structure as a presentation object (FormatID=5). Apparently not documented in the MS-OLEDS document.

A presentation object can have these types:

  • FormatID=0: Empty.
  • FormatID=5: Contains an image, or a clipboard object.

Related formats

In addition to the arbitrary payload data, these standard formats may be contained in an OLE 1.0 object:
