Open onenote cache file

Based on my test, OneNote file wouldn't be deleted when I uninstall Office suites. I'd like to suggest you search your notebooks' name on the File Explorer search box to see if you can find them. If you still can't find them, that means they may be deleted by other operations. As a workaround, I'd like to suggest you save your notebooks into OneDrive or SharePoint to keep them safe.

Thank you for the continued research. Which version of Office suite did you uninstall? Any word from the "Product" team on the ability to rebuild a notebook from onecache and onebin files? I'd like to suggest you follow my suggestions above to search your notebook on your computer.

If you can't find it, it is not feasible to recover them via cache files. I appreciate your understanding. Victor Wolters. I have the same question Report abuse. Details required :. Cancel Submit. Hi Victor, If you save your notebooks on your computer, I'd like to suggest you use OneNote client open your notebooks from your notebook saving path. Thanks, Neo.

Apart from all this, like any other application, OneNote also uses cache to store data temporarily. But it has some issue that if it is not handled properly, OneNote will become unnecessarily large. So, if the cache of OneNote become corrupted, then one has to delete it manually. Therefore, it is really important for the user to clear OneNote cache in , , on regular interval to avoid any type of corruption issues.

The cache folder is really important for the users as it stores all data in a reduced format due to which its execution of some particular instructions becomes fast during web access. But, if it is occupying a large amount of space on the system, then deleting it would be a right choice.

Moreover, if it gets corrupted, then it can badly affect the performance of Outlook. However, if you have offline notebooks that have not synced recently, you will lose unsyned changes " and get the options to " delete cache " , " make a copy " or " cancel ". If i click "make a copy" i get the message "OneNote cannot delete the notebook cache file. Verify that you have write access and try again".

When i click the "delete cache" mentioned above i get the first message again. This thread is locked. You can follow the question or vote as helpful, but you cannot reply to this thread. I have the same question Since then a varied career has included being part of the team building the world's first solid state 30KW HF radio transmitter, writing electromagnetic modelling software for railguns, and testing the first ADSL equipment in the UK.

I can write on my tablet screen and have my handwriting recognised, I can record audio that's time-synced to my typed notes, I can clip in sections of Web pages or dialog boxes I want to use as screen grabs, I can print in documents to annotate I put everything in OneNote. And I've never lost anything because OneNote never makes you save a file by hand. It autosaves everything into a local cache file every few seconds, backs that up to another local file by default once a day and then syncs the changes to the master notebook - which can be on your PC, on a server, on SharePoint, on a cloud storage service that you map as a drive, on a USB stick or on SkyDrive where I can view or edit the notebook in the browser or anywhere else you can connect to - as soon as it's available.

You can make changes offline and they're just magically updated when you get back online - so I can take notes on my teeny tiny VAIO Series P over lunch then read them on my big-screen big-keyboard Dell Studio when I want to work with them or write them on my big keyboard and refer to them on my VAIO.

If you only use OneNote on one PC, you end up with three levels of local backup; but most people who use OneNote share notebooks between PCs, so that local caching is even more useful. What you find in your backup may not be enough if you get the rare error message that tells you the cache is corrupted and OneNote has to delete it, rebuild it and throw away any unsynced data.

This happened to me a few times thanks to an interaction between OneNote and the beta version of OneNote again - this is why it's called beta software and it's fixed in the shipping version so I haven't had this problem myself in months, but I've seen the odd question about this online recently so I wanted to list what worked for me.

Usually the error was on a machine that had a secondary copy of the notebook, not one with unsynced changes so I just let it rebuild and carried on working. Once I got the error before I'd had a chance to sync and I knew there was one page that I would have lost. I grabbed the original. It takes good timing but, with the mouse in the right area of the screen, I could right-click, choose Save As and get a copy of the notebook before the message about deleting the cache came up NOTE - at no point did I click on the option to delete the cache; once you do that it's gone for ever.
