Documentation on formats of stream objects in OLE files.

Parth Gupta 160 Reputation points


I am trying to parse a ".doc" file (Microsoft Word 97-2003 Document) (OLE), and I am looking for some documentation.

I found the following reference:

Through these documentations, I can parse the sectors, the directory structure, the FAT and mini FAT, etc. I am, however, looking for documentation on the format of streams like 'Data', '\x05DocumentSummaryInformation', '\x05SummaryInformation', '\x01CompObj' and others.

Kindly lead to technical documentation of the above formats (if any).
