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
 
 
== 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:
 
** [[Word Document (DOC)]]
 
** [[Excel Spreadsheet (XLS)]]
 
** [[Powerpoint Presentation (PPT)]]
 
* [[Thumbs.db]]
 
* [[Jump Lists]]
 
* StickyNotes.snt
