Where ARE OneNote files saved?

Frequent Contributor

Today I was using OneNote to save some notes form an online course I'm going through. I realized that I was putting all these notes into the wrong OneNote notebook. I searched to see if I had a different OneNote notebook for the new that I wanted to create. There was none, so I proceeded to create it.

 

Only OneNote than complained to me, saying that a OneNote notebook by that name, already existed. 

 

Oh yeah, well then where in heck is it? I looked in my OneDrive for it (I have a Microsoft 365 Family Edition license). According to this web page all OneNote files end with a file extension that looks like this

 

.one*

 

So, I looked at the root level of my OneDrive for all files ending in .one*. It didn't find anything.

 

Huh?

 

The mystery is getting larger. When I look inside OneNote, to say add a new notebook, it will show me the names of the available OneNote notebook. But when I try to find them searching using OneDrive - no way. Nothing exists anywhere. I'm pretty sure that OneNote does use OneDrive for saving OneNote notebooks. I'm sure of this because when I use my Windows 10 desktop, or Window 10 laptop, or my Android phone, I can find all of those notebooks as notebooks I could add. So, what in heck is going on here? Does OneNote obfuscate the file name for some reason of it's own?

Did you ever find the answer to your question? I am having this question now. @Rod Falanga 

@thompstr not really, no. I've found only 1 file with an extension of .one. And I have about a dozen OneNote files, all on my OneDrive. I've no idea how that happened.
