'''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 [[Microsoft Write|Write]] and [[Cardfile]] files, and presumably in various third-party document files from that era.

== 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 arbitary payload data, these standard formats may be contained in an OLE 1.0 object:
* [[BMP|DIB]]
* [[Windows Metafile|WMF]]
* [[Windows DDB|DDB]]
* [[Windows clipboard]]

* [[Microsoft Compound File]], a.k.a. OLE2 - Successor format (sort of)

* Microsoft's documentation of [[Cardfile#Specifications|Card File Format]] includes an outline of the format.
