How can I extract files that I have embedded in a OneNote 2010 .one file? If there is no easy way to do that, is there a way to get a list of all of them in the notebook or section so it is easy to grab them all and dump them to disk?

Yeah I knew that was the running answer in some of the forums. I was hoping that some other SuperUser had figured it out. – Russell S. Pierce May 25 '13 at 0:11
Perhaps if the format's internal details are known or have been reverse engineered someone might have come up with an extraction utility. Quite a niche requirement though so wouldn't hold my breath. – Karan May 25 '13 at 1:06
I'm kind of shocked they haven't been. When files aren't embedded the .one file format seems like all other Office files from 2010, a zip file with a file structure and XML inside. – Russell S. Pierce May 25 '13 at 2:13
So it's ZIP based too like the other OOXML formats? Then what happens to the embedded files? Aren't they accessible when you extract the archive? – Karan May 25 '13 at 2:29

The only way I found (OneNote 2010):

  1. Select your OneNote page(s)
  2. File -> Send -> E-mail Page
  3. All of your embedded files will be in a new email as attachments. Now you can extract them from there.
