Frequently Asked Questions

Where are OneNote backup files stored on Windows by default?

By default, OneNote backup files are stored in C:\Users\<user>\AppData\Local\Microsoft\OneNote. You must replace '<user>' with your actual Windows account username to find the correct directory.

Why am I getting OneNote error 0x2BDF5F?

This specific error typically occurs when a section file, attachment, or the cache directory itself has been moved, renamed, deleted, or is otherwise inaccessible, preventing OneNote from synchronizing properly.

How do I view the AppData folder if it is hidden in File Explorer?

The AppData folder is hidden by Windows by default. To view it, open File Explorer, click the 'View' tab at the top of the window, and check the box next to 'Hidden items'.

Does restoring the default folder path always fix OneNote sync issues?

While restoring the default location helps if the folder path was accidentally altered, it may not resolve all sync problems. You should also check your folder permissions, ensure you have an active internet connection, and verify the notebook is not corrupted.
