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. – russellpierce 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. – russellpierce 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.
  • On Mac this only works for images. PDFs are not added to the mail. :( – Fuzzy76 Jun 18 '18 at 13:11

In OneNote 2016, it is possible to click in the note when it is open, and press Ctrl+C to copy all.

If there is a large number of attachments, it may lag for a few seconds.

Then you can paste into a file explorer window to drop all of the embeds into the folder.
