(OLE Compound File)
 
 
Line 1: Line 1:
The '''OLE Compound File (OLECF)''' is used in other file formats as its underlying container file.
+
#REDIRECT [[Talk:Word Document (DOC)]]
It allows data to be stored in multiple streams.
+
 
+
The OLECF is also known as:
+
* OLE2 file
+
* Compound Binary File (current name used by [[Microsoft]])
+
* Compound Document File (name used by [[OpenOffice]])
+
 
+
== 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 content.
+
 
+
== 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 the streams through a directory and the blocks that are assigned to the stream using multiple allocation tables.
+
 
+
The OLECF is used to store:
+
* [[Microsoft Office]] 97-2003 documents:
+
** [[Word Document (DOC)]]
+
** [[Excel Spreadsheet (XLS)]]
+
** [[Powerpoint Presentation (PPT)]]
+
* [[Thumbs.db]]
