Embedded OLE data is stored in the host-defined format. It means that
depending on the data the structure of directory entries can be
different.
For example:
XLS:
CompObj
DocumentSummaryInformation
SummaryInformation
Workbook
DOC:
CompObj
DocumentSummaryInformation
SummaryInformation
WordDocument
ZIP:
CompObj
ObjInfo
Ole
Ole10Native
TEXT:
???
VISIO
???
PDF
???
.....
In case if the embedded entry is a xls, ppt or doc you can save it with
appropriate extension and it will be "real" office document. You
should be able to open it in MS Office or by POI.
I'm note sure about ZIP, text or other formats. I searched the spec
but didn't find a clue. My advice is to look at CompObj. Every embedded
entry seems to have it. Try to parse this data, may be you will figure out the
pattern.
