How to Open and Import Old OneNote Files into OneNote for Windows 10
Product
Microsoft OneNote
Device & OS
Windows 10
Scenario
Trying to access legacy local OneNote notebooks (.one files) but finding that the Windows 10 version of OneNote does not support local files.
Observed behavior
OneNote for Windows 10 cannot directly open or convert old local notebook files because it exclusively relies on cloud-based notebooks via OneDrive.
Before you start

Ensure you have a Microsoft account with available OneDrive cloud storage, and that you have downloaded the classic desktop version of OneNote (OneNote 2016) to your computer.

Use OneNote 2016 to Sync Local Notebooks to OneDrive

Because OneNote for Windows 10 does not support local files, you must use the classic OneNote 2016 application to open the older files and move them to OneDrive.

Microsoft removed local notebook support in OneNote for Windows 10, meaning there is no direct way or standalone converter to open your old files natively in the newer app.

To bridge this gap, you will use OneNote 2016 as a temporary gateway to upload your local notebooks into Microsoft's cloud ecosystem.

1
Install or open OneNote 2016

Launch the OneNote 2016 desktop application. If you do not have it installed, download the desktop version of OneNote for free from the official Microsoft website.

2
Open the old local notebooks

In OneNote 2016, click on 'File', select 'Open', and click 'Browse' to locate and open the legacy local notebook folders stored on your PC.

3
Sign in to your Microsoft account

Ensure you are signed in to OneNote 2016 with the same Microsoft account (and corresponding OneDrive) that you plan to use with OneNote for Windows 10.

4
Move notebooks to OneDrive

Click 'File', select 'Share', and choose your connected OneDrive account. Click the 'Move Notebook' button and wait for the synchronization process to finish completely.

5
Open in OneNote for Windows 10

Launch OneNote for Windows 10, click on 'More Notebooks' (or the notebook dropdown list), and select your newly synced notebooks directly from OneDrive to open them.

Use OneNote 2016 to Sync Local Notebooks to OneDrive
Synchronization time varies: Depending on the size of your old notebooks and the speed of your internet connection, the initial sync to OneDrive might take some time. Keep OneNote 2016 open until the sync is fully complete.

Frequently Asked Questions

Is there a standalone converter tool for older OneNote local notebooks?

No, Microsoft does not provide a separate converter tool. The only officially supported method to convert local notebooks is to open them in the classic OneNote desktop app (OneNote 2016) and move them to OneDrive.

Can I use OneNote for Windows 10 without a Microsoft OneDrive account?

No. OneNote for Windows 10 is designed exclusively around cloud storage and requires a Microsoft account with OneDrive or a SharePoint account to create, open, and save notebooks.

Where can I safely download OneNote 2016?

You can safely download the classic desktop version of OneNote directly from Microsoft's official website. It is available as a free download even if you do not have an active Microsoft 365 subscription.

Why did my notebook end up in OneDrive instead of locally in OneNote?

OneNote for Windows 10 does not store files locally on your hard drive. It streams notebooks directly from your OneDrive account. Moving the file to OneDrive is a necessary step so the new app can locate and load your notes.
