olefile (formerly OleFileIO_PL)
|
|
===============================
|
|
|
|
[olefile](http://www.decalage.info/olefile) is a Python package to parse, read and write
|
|
[Microsoft OLE2 files](http://en.wikipedia.org/wiki/Compound_File_Binary_Format)
|
|
(also called Structured Storage, Compound File Binary Format or Compound Document File Format),
|
|
such as Microsoft Office 97-2003 documents, vbaProject.bin in MS Office 2007+ files, Image Composer
|
|
and FlashPix files, Outlook messages, StickyNotes, several Microscopy file formats, McAfee antivirus quarantine files,
|
|
etc.

Download/Install
|
|
----------------
|
|
|
|
If you have pip or setuptools installed (pip is included in Python 2.7.9+), you may simply run **pip install olefile**
|
|
or **easy_install olefile** for the first installation.
|
|
|
|
To update olefile, run **pip install -U olefile**.
|
|
|
|
Otherwise, see https://bitbucket.org/decalage/olefileio_pl/wiki/Install
|
|
|
|
Features
|
|
--------
|
|
|
|
- Parse, read and write any OLE file such as Microsoft Office 97-2003 legacy document formats (Word .doc, Excel .xls,
|
|
PowerPoint .ppt, Visio .vsd, Project .mpp), Image Composer and FlashPix files, Outlook messages, StickyNotes,
|
|
Zeiss AxioVision ZVI files, Olympus FluoView OIB files, etc
|
|
- List all the streams and storages contained in an OLE file
|
|
- Open streams as files
|
|
- Parse and read property streams, containing metadata of the file
|
|
- Portable, pure Python module, no dependency
|
|
|
|
olefile can be used as an independent package or with PIL/Pillow.
|
|
|
|
olefile is mostly meant for developers. If you are looking for tools to analyze OLE files or to extract data (especially
|
|
for security purposes such as malware analysis and forensics), then please also check my
|
|
[python-oletools](http://www.decalage.info/python/oletools), which are built upon olefile and provide a higher-level interface.

|
History
|
|
-------
|
|
|
|
olefile is based on the OleFileIO module from [PIL](http://www.pythonware.com/products/pil/index.htm), the excellent
|
|
Python Imaging Library, created and maintained by Fredrik Lundh. The olefile API is still compatible with PIL, but
|
|
since 2005 I have improved the internal implementation significantly, with new features, bugfixes and a more robust
|
|
design. From 2005 to 2014 the project was called OleFileIO_PL, and in 2014 I changed its name to olefile to celebrate
|
|
its 9 years and its new write features.
|
|
|
|
As far as I know, olefile is the most complete and robust Python implementation to read MS OLE2 files, portable on
|
|
several operating systems. (please tell me if you know other similar Python modules)
|
|
|
|
Since 2014 olefile/OleFileIO_PL has been integrated into [Pillow](http://python-pillow.org), the friendly fork
|
|
of PIL. olefile will continue to be improved as a separate project, and new versions will be merged into Pillow
|
|
regularly.
|
|
|
|
|
|
Main improvements over the original version of OleFileIO in PIL:
|
|
----------------------------------------------------------------
|
|
|
|
- Compatible with Python 3.x and 2.6+
|
|
- Many bug fixes
|
|
- Support for files larger than 6.8MB
|
|
- Support for 64 bits platforms and big-endian CPUs
|
|
- Robust: many checks to detect malformed files
|
|
- Runtime option to choose if malformed files should be parsed or raise exceptions
|
|
- Improved API
|
|
- Metadata extraction, stream/storage timestamps (e.g. for document forensics)
|
|
- Can open file-like objects
|
|
- Added setup.py and install.bat to ease installation
|
|
- More convenient slash-based syntax for stream paths
|
|
- Write features

especially the [OLE overview](https://bitbucket.org/decalage/olefileio_pl/wiki/OLE_Overview) and the
|
|
[API page](https://bitbucket.org/decalage/olefileio_pl/wiki/API) which describe how to use olefile in Python applications.
|
|
A copy of the same documentation is also provided in the doc subfolder of the olefile package.
