What is a .ONETOC2 files

A .ONETOC2 file is a cache file generated by Microsoft OneNote to optimize the performance and organization of notebook sections. It stores metadata and indexing information, serving as an index for the associated notebook. These files are hidden from users and are automatically managed by OneNote to enhance overall application efficiency. They play a crucial role in facilitating quicker access to specific sections within a notebook. Users typically interact with OneNote through its graphical interface without directly engaging with .ONETOC2 files.

How to read the .ONETOC2 file extension?

Reading a .ONETOC2 file extension directly may not be practical, as these files are generally meant for internal use by Microsoft OneNote and contain metadata and indexing information for optimizing notebook performance. Instead, interacting with the content of OneNote notebooks is typically done through the OneNote application or programmatically using the OneNote API. If you have specific needs related to the data stored in .ONETOC2 files, consider exploring the capabilities of the OneNote API or related libraries that can provide access to the organized information within the notebooks without directly parsing the .ONETOC2 file. If necessary, you can use our other applications and convert ONETOC2 files to other formats.
