What is a ONETOC2 file (a file with file extension ONETOC2)?

Files that contain the .onetoc2 file extension are most commonly associated with the OneNote personal note-taking software application that is distributed by the Microsoft Corporation. The software allows users to take notes just as they would in a normal paper-based notebook, but the notes are created in a computing environment and, as a result, are more manageable and easier to organize.

The ONETOC2 files that are created by the software contain a Table of Contents that organizes the collection of notes that are located in an associated OneNote notebook. This makes it easy for the user to reference the notes that they have created with the software program.
