After moving notebooks to OneDrive or SharePoint, OneNote treats them as cloud notebooks. The “files” seen in File Explorer (or in the OneDrive sync folder) are internet shortcut links pointing to the real notebook in the cloud, not the actual .one section files.
Where the notebooks are stored:
- If moved to OneDrive, they are stored in the OneDrive account online (for example under the OneNote Notebooks area in OneDrive).
- If moved to SharePoint or Microsoft 365, they are stored in that SharePoint/Teams site’s document library.
OneNote keeps a cached copy of cloud notebooks on the device so they can be used offline, but this cache is managed internally by OneNote and is not meant to be used as normal files.
To move a local notebook to the cloud (and thus know exactly where it is stored):
- In OneNote desktop, open the local notebook.
- Go to File > Share.
- Pick a web location such as OneDrive or SharePoint, then select Move Notebook.
- OneNote uploads the notebook and sets up direct sync.
- After the move, the old local notebook is no longer connected or synchronized and can be deleted.
Having a copy on the PC:
- OneNote automatically caches a local copy of cloud notebooks so they are available offline; this is the supported way to have them “on the PC.”
- Do not use Windows Explorer to copy or move .one files into the OneDrive folder. This can cause sync errors because OneDrive and OneNote would both try to sync the same files. Instead, always use File > Share > Move Notebook in OneNote to place notebooks in OneDrive/SharePoint.
If local notebooks seem to have disappeared after moving:
- They are now in the chosen OneDrive/SharePoint location (visible via a web browser in OneDrive or the SharePoint document library).
- The entries seen locally are shortcuts representing those cloud notebooks.
