Opening OLE Files

The OLE file type is primarily associated with Microsoft Office.

OLE	File extension: OLE
	File type:	compound binary file

What is an OLE file?

OLE files mostly belong to Microsoft Office. OLE files use the Object Linking and Embedding technology to combine data from different sources into one container. They rely on a compound file binary format common in Microsoft Office products.
In practice, these files store embedded objects such as charts, images, or segments of other documents. They also maintain links to external sources so that changes in the source can update the embedded content.
Key details summarized by FilExt.com include:

Embedding: Objects are stored together with the main document.

Linking: Connections to external files allow content to remain current.

Binary Structure: Multiple data streams are maintained within a single file.

FilExt.com note: More details are available at Microsoft Office Word.

How to open an OLE file

You need a suitable software like Microsoft Office to open an OLE file. Without proper software you will receive a Windows message "How do you want to open this file?" or "Windows cannot open this file" or a similar Mac/iPhone/Android alert. If you cannot open your OLE file correctly, try to right-click or long-press the file. Then click "Open with" and choose an application. You can also display a OLE file directly in the browser:. Just drag the file onto this browser window and drop it.

OLE file extension format:

Each file has a definite file format, that is, how the stored data is arranged in the file. Often, the file format can be deduced from the file extension or the initial bytes (called the signature). Frequently, however, one file extension is used by different programs for different file formats, and one file format for different file extensions. If there are problems opening a file, you must first determine the file format used. Below you will find our evaluation of the OLE files:

OLE is a very widely used file extension. The file type mainly uses a special format. The following file formats are most commonly found in OLE files:

• 90% of all OLE files utilize the Microsoft Compound File format, also known as Composite Document File format or OLE2 compound document format. This Windows file format has features similar to those of a filesystem format with virtual files and subfolders. The file signature of compound files is defined as D0 CF 11 E0 A1 B1 1A E1, so the first character of a file looks like "DOCFILE". These files are binary files, so they do not contain text, but only cryptic characters. OLE files are between 4 KB and 5 MB in size. The file type was developed 10 years ago and is still in use today. Files like these are sometimes connected to found, sector, carved, olefileatsector, excel and object.
• 3% of all OLE files use the same file format, which have the signature 7B 5C. The contents of these files are easily readable with a text editor. The files are 30 KB to 2 MB in size, with a median of 270 KB. The following keywords are characteristic: objclass, objdata, object, objemb, objh, objw, 00000000, 01050000 and 02000000.

All other OLE files (7%) have no uniform format, often, for example, ZIP. Drag & drop your file here to see the file format and a preview of your OLE file!
