Copy the "My Notebook" folder to another disk. By
default it is a subfolder of "My Documents".
If you've changed the default location, then copy
whatever folder is specified in Tools | Options | Open
and Save | My Notebook.
The other parameters listed there that aren't files or
sections might be useful in a backup as well, for example
all of the internal OneNote backups made in the "Backup
Folder" value.

Can anybody give me advice on how to save my current
OneNote postings and structure and reinstate them -
notebooks, sections, pages, etc., when I reinstall.
