TBB format

Thinkbook's backup file has the extension tbb.
You stated "They are just XML with the .tbb extension so ThinkBook knows to treat them as backups.",
but this doesn't seem true.
If I look at the file, it looks like it is somehow encrypted and not human (or XML editor) readable.
This is the same for local and dropbox backups.

Would you like to give some more information about the format?

I would like to write an application for Mac and Windows which can handle the notes.
I want to use the backup file, because I assume it has more information.
E.g. the text export has no information about the todo and question finder, only their results.

    Thanks, now it's readable - and it's more content than expected.
    Is somewhere a documentation about it or need I to reverse engineer it?

    There isn't any documentation on it. It's just me doing this so I've never felt the need. I don't think there is anything too tricky in there, I wrote it with the aim that users could get the information out of a backup using an XML editor/reader.
