Recover information from OneNoteOfflineCache.onenote

Question

Hello, I'm in a bit of a crisis because I just accidentally deleted a bunch of corrupted cache files. I seem to have lost all my work from the past 2 weeks. This is quite a bit of work to reduplicate. I didn't realize that the way I set up my onenote with only syncing manually online to Windows Live meant that I didn't have any local copy of my onenote file apart from the offline cache. Then when the offline cache went corrupt, everything was lost.

Anyway, because I didn't realize my setup was like this, when I started OneNote and it told me I had corrupt offline files, I allowed OneNote to delete them because I thought I had another local copy. So then I used a restoration program to pull the deleted files from the hard drive and I've zipped them up.

Is it possible to recover any data from these files? When I open them in WordPad, they are nonsense. Is there any program I can use to open them up? I'd be happy to send them to someone if they thought they could recover some information. I have several long sections of text that I'd be really happy to recover.

Thanks.

UPDATE: Now I have a recovered OneNoteOfflineCache.onenote and need to open it somehow with Onenote. See last post

Answer 1

What I have is a bunch of files that were

stored in my OneNoteOfflineCache_Files with really long names of

alphanumerics. They don't have file extensions. It looks like some of

those files are JPGS or other graphics. I was hoping some of them

were text, but maybe all the text is stored in the

OneNoteOfflineCache.onecache file.

Exactly the latter.

What's stored in "OneNoteOfflineCache_Files" are only copies if embedded

files (images, docs, audio files etc.).

They are if no use at all in your current situation.

I don't have backups turned on. My mistake. I was using another backup solution that didn't work out because I didn't realize OneNote only used a local cache instead of a local copy of my notebook.

I've actually managed to find a "OneNoteOffliceCache.onenote" file through system restore from yesterday afternoon, but I can't seem to open it with OneNote. If I open it in WordPad, I see some of my text, so I can try to mine through it and pull some of what I lost out of it, but there must be a way for a support person to open this file as a notebook. Can anybody help with this?

Answer 4

Normally you should have local backups, automatically created by Onenote. To find under File | Info | Open Backups.

The rules are under File, Options, Backup.

Answer 5

Let me clarify one thing. I don't have the OneNoteOfflineCache.onenote file. All the files I could recover with that filename were too old. What I have is a bunch of files that were stored in my OneNoteOfflineCache_Files with really long names of alphanumerics. They don't have file extensions. It looks like some of those files are JPGS or other graphics. I was hoping some of them were text, but maybe all the text is stored in the OneNoteOfflineCache.onecache file. If that's the case, I don't know how to recover it because it looks like it was just written over - not deleted.

Am I stuck?
