OneNote keeps backup copies of your
notebooks. These backup copies of notebooks are maintained in the form
of sections. The sections have the file extension .one.
For example, the backup copy of a section called “Production” is called
“Production.one.” To help identify when backup copies were made,
OneNote lists the date they were made after the backup name.
To view the backup copy of a section, click File,
choose Info, and click the Open Backups button. Then, in the Open
Backup dialog box, open the folder with the name of your notebook,
select the backup section you want to open, and click the Open button
(in the Open Backup dialog box, sections in section groups are stored
in a subfolder named after the section group).
After you open a backup copy of a section, OneNote places a tab on the Navigation bar called Open Sections. With this tab, you can switch back and forth between backup sections you opened and your OneNote notebook.
You can copy notes, pages, and the section itself from the backup copy into a notebook.

OneNote Options dialog box to open the Backup folder in Computer.
