Binary files format of MS OFFICE

Is this what you need?

What you are asking about is file signature/file header info. This is data that the normal user does not normally see. All you need to do is open the file with a hex editor and view the hex code. The first part of the file is a unique code which identifies what kind of file it is. The file signature for Microsoft Office is D0 CF 11 E0 A1 B1 1A E1 at offset 512 or 200 hex is a sub file signature that indicates if it is a word, powerpoint, excel document.

In the link above is a screen shot of a word document in a hex editor and the file signature is highlighted in red.

This link is a list of very common file headers. If you don't find the header info here then I would suggest searching google for file signature.

Thanks for your answer! I find this information very usefull to begin with and I would really appreciate if you could send me more.

Furthermore, I have already asked Microsoft Team for the binary files format of MS OFFICE and they are suppossed to send them to me.

I will send them to you as well.

Best wishes,

Hi,

a great source of information for file formats (and not just signatures) is http//www.wotsit.org
You can find some other information sources on the Forensics Wiki (http//www.forensicswiki.org).
