Hello,

As mentioned here:

https://learn.microsoft.com/en-us/openspecs/windows_protocols/ms-oleds/fdc5e702-d09e-4344-a77f-eb079d41f23f

There are 2 versions of Microsoft OLE Compound File: OLE1.0 and OLE2.0 Formats

I know the magic number of the OLE2.0 Format is: Hex: D0 CF 11 E0 A1 B1 1A E1

But can't find the official info on the magic number of the OLE1.0 Format.

Anyone knows anything about that? Thanks in advance :)

    Hi @Peter Volz ,

    OLE 1.0 and OLE 2.0 files share the same file signature(D0 CF 11 E0 A1 B1 1A E1).

    Best Regards.
