Hi Patrick,

What you listed would be different variants of the same file format, not a different format (i.e. the details are evolving but the
structure is pretty much the same). It's similar to the RTF spec in that regard in that it changes with each version of Word as
well and to the .doc, etc file formats. New versions of each app may have features not backwards compatible but the file format is
considered to be 'the same'. With betas, it's often the forward (between beta-test versions) compatability that gets to be the
issue.

It would have been nice if MS's 'error' dialogs in TR2 were looking at the headers in the file to be a bit more specific on what
they're seeing as the problem. It might also be an interesting exercise to see if the claims on being able to recover files when
one part breaks from the .---x (zipped) contents would be doable in trying to save the content from a pre B2TR file by moving them
to a new .---x structure.

Definitely different. Files created in B1 and B1TR don't open in B2TR
anymore, they actually produce a corrupt file error message. B2TR uses
the XML file formats according to the Ecma draft v1.4, B2 used 1.3. B1TR
and B1 were earlier versions.
