Change Backup and Cache Locations in OneNote Desktop
Use this method if you are running the desktop version of OneNote (formerly OneNote 2016) and need to redirect where local cache and backup files are saved.
Unlike the Windows 10 app version, the full desktop version of OneNote allows you to customize exactly where your files are backed up and cached on your local drive.
Open the OneNote desktop application. Click on 'File' in the top-left corner of the ribbon, then select 'Options' at the bottom of the menu.
In the OneNote Options dialog box, click on 'Save & Backup' from the left-hand sidebar menu.
Under the 'Save' section, select either 'Backup Folder' or 'Cache file location' from the list, then click the 'Modify' button. Browse to your preferred local folder on your computer and click 'Select'.

Frequently Asked Questions
Can I open OneNote local cache files directly?
No, OneNote cache files cannot be opened or read directly. They are system files used internally by the application to manage offline edits and improve loading speeds.
Why should I use OneNote Desktop instead of OneNote for Windows 10?
If you want to ensure that your cache files and backups are saved in a specific local directory (like a secondary hard drive), you should use the OneNote Desktop application. OneNote for Windows 10 does not allow you to change the cache location.
Does changing the backup folder move my original OneNote notebook?
No. Changing the backup folder in OneNote Options only alters where the automatic backup copies are saved. Your actual notebook remains in its primary location, which is typically your OneDrive or SharePoint account.
