The Object Linking and Embedding (OLE) Compound File (CF) is used in other file formats as its underlying container file. It allows data to be stored in multiple streams.
The OLECF is also known as:
- Compound Binary File (current name used by Microsoft)
- Compound Document File (name used by OpenOffice)
- OLE2 file
Contents |
MIME types
Because the OLECF by itself is just a container it does not use a mime type. A mime type assigned to an OLECF refers to its contents.
File signature
The OLECF has the following file signature: hexadecimal: d0 cf 11 e0 a1 b1 1a e1
The OLECF has no distinct footer.
Contents
The OLECF uses a FAT like file system to define blocks that are assigned to the stream using multiple allocation tables. It uses a directory structure to define the name of the streams.
The OLECF is used to store:
- Microsoft Office 97-2003 documents:
- Thumbs.db
- Jump Lists
- StickyNotes.snt

Microsoft Compound Document File Format (This is actually the OpenOffice specification)
