FileCorruptedException when opening OneNote files


A FileCorruptedException is thrown when trying to open a .one document with Aspose.Note.

The exception message is “The MD5 hash is not correct for referenced struct.”

The .one file was created with MS OneNote 2016 and can be opened with OneNote without any problems.

This exception is thrown when using Aspose.Note for .NET 17.8 as well as the lastest available version 18.9, when executing the following code:

// filePath points to the file: Section
var fileStream = new FileStream(filePath, FileMode.Open);
var doc = new Aspose.Note.Document(fileStream);

Hi there,

Is there an ETA on this issue?

Thanks in advance…



We are working on this issue and it is not resolved yet. We will update you here soon.


Just to say one more person interested in this bug fix (btw. I also opened more than few OneNote tickets, all ending with bug creation). If you can accelerate a bit with OneNote that would be great (this was created 3 months ago :frowning: )
