Where are the OneNote App local files stored in Windows 10? (Surface 3)

I want to find where the App Stores the local files so I can open them in the Desktop Version.

The local files, as you call it, are local cache files, not the real notebook.

But you can try to outwit Onenote 2016.

The cache files for Onenote 2016 are in a file and in an additional folder in

C:\Users\<user>\AppData\Local\Microsoft\OneNote\16.0

The corresponding files of the App you'll find in

C:\Users<user>\AppData\Local\Packages\Microsoft.Office.OneNote_8wekyb3d8bbwe\LocalState\AppData\Local\OneNote\16.0

Before overwriting the Onenote 2016 files close all notebooks in Onenote 2016 and then close it.

On your own risk ;-)

EDIT:

The 1st structure is valid only for Onenote 2010 and 2013. Onenote 2016 has the same structure as the App.

Bernd,

I have a similar problem I hope you can help with.

I use one note 2016 (not the desktop version) to survey, sketch and measure buildings on site. Recently I opened one note to find they were not there??? My onedrive storage wasn't large enough, but it appeared to save the files locally as evertime I opened onenote they were listed in the left hand column so I left things as they were. So the situation is I don't have copies on one drive and cannot find them locally on my windows surface.

How do I actually open files in the cache folder, the extension they have is .bin and one note does not recognise them.

WI don't understand how/why they have suddenly disappeared??

Thank you in advance

Brian.

At first you need an installed Onenote 2016.

Then you can try to copy the cache folder in the App's 16.0 folder over the cache folder of Onenote 2016's 16.0 folder. The paths you see in my last reply.

Then start Onenote 2016.

I'm having the same issue. Followed the instructions (which I found very helpful)  I loaded Outlook 2016 on a new machine, and logged in with my Microsoft account. I closed all the notebooks that where open and copied the cache from the OneNote APP to the OneNote desktop 2016. It says "OneNote cannot access the notebook cache file. It may be corrupted. OneNote will restart and create a new cache file." I pulled the cache folder from a backup I did a month ago. I believe the files are good. is there any rights or other files I need to move? 

Thanks in advance.

I've been messing around with it some more I think the problem has something to do with the header file located in the cache directory. If you copy the header over it doesn't work. If you use the one that is currently there it still doesn't open but doesn't provide a corrupt error winder either. If you delete it all together and open Onenote, No issues but opens all blanks. 

TLDR; what does the header do and can it be modified to open?

Hello all,

I have been using OneNote for a long time with relatively no issues.  I recently got a surface 3 to take out into the field with me and got my first taste of the OneNote App that comes pre-installed on the device.  As far as performance in the field is concerned it worked great.  The problem now is I cannot seem to get some of the note sheets that I created to sync.  My thought is that the syncing is getting mixed up as they are extremely large because contain many pictures.  What I would like to do is find the files locally on the device, copy them using an external hard drive or something, and open them on my Desktop or even in the OneNote 2016 on the Surface 3.  Problem is I can't find the local files for the app.  Please help.

TLDR; I want to find where the App Stores the local files so I can open them in the Desktop Version.

I appreciate your help.

Me too was not able to sync some of my OneNote APP notebooks. That's little tricky to create new empty notebook in OneNote app and then moving the sections from our problematic notebook to this newly created notebook. But if we do so, one may be able to sync the new notebook with all the required sections. However, still sometime one simply can not move a required section to the newly created (empty) notebook.

Hence, instead simply follow the steps.

1.  Go to OneNote App cache files from C:\Users<user>\AppData\Local\Packages\Microsoft.Office.OneNote_8wekyb3d8bbwe\LocalState\AppData\Local\OneNote\16.0
2. Copy all the (three) folders inside the folder '16.0'.
3. Now go to OneNote 2016 (.exe program) cache file location                                                          C:\Users\<user>\AppData\Local\Microsoft\OneNote\16.0
4. Paste all (three) the copied folders to this location and overwright all the files already available there.
5. Now try to sync all notebooks.
6. Some notebooks (most probably the 'same' notebooks) may not be able to sync. It will show the error 0xE0190190.
7. But as now you got the notebooks (at least offline) into the .exe program, it's quite easy to play with anything of it.
8. Now it's not that hectic to create a new 'Offline' (Windows Explorer (/file Manager) 'browsable') OneNote-notebook file and move your required (screwed) sections to it.
9. After that done, simply move this file to OneDrive.
10. Now again try to sync it with OneNote 2016 (.exe program) (press shift+F9), it should work!

And then, F***ing OneNote APP would have no b*als to make it offline (again!).

First of all thanks for helping me find the APP notes. I did what you suggested and thankfully I have some of the notes again in the Note 2016. But they still do not sync and it would be a major pain to copy every section of every note to a new note. Is there anyway to copy the whole note ?

This is not a very good system ! Also anyone know where the files should reside on onedrive ? My problem was that  one drive was playing up so I deleted everything and put the files back. It helped onedrive, but screwed up onenote sync.

Cheers,

Paul

Hi Bernd

My OneNote App crashed and the below location is empty

C:\Users<user>\AppData\Local\Packages\Microsoft.Office.OneNote_8wekyb3d8bbwe\LocalState\AppData\Local\OneNote\16.0

Is there any way to recover my files?
