File extension .ONETOC2

| Microsoft OneNote Table Of Contents Format | Microsoft | Settings Files |
The .onetoc2 file extension is an index for OneNote notebook files. This type of file format contains a table of contents listing page titles and navigation details that are stored in a Microsoft OneNote Notebook. The .onetoc2 file is automatically generated when the notebook is saved and does not need to be manually generated by the user.
Compatibility
The .onetoc2 file can only be opened and edited with Microsoft OneNote, which supports the Windows and macOS operating systems. While other non-Microsoft applications cannot open or edit .onetoc2 files, there may be alternatives that can open similarly formatted files such as .onepkg, .onetoc, and .one.
Programs for WINDOWS system
After installing the required software, the operating system will usually automatically associate an unknown file type (in this case .ONETOC2) with the new application. If this does not happen, we can help the system a bit by selecting the software for it, which it should always use to open files with the .ONETOC2 extension.
When choosing the software we can select the system to use this software every time.
Remember!
Using it for the first time it is good to check whether the .ONETOC2 file opened in the application can be read by us and opens in a way that allows us to use it. If everything is in order, select this option the next time you open a file with the .ONETOC2 extension. However, if the file has not opened correctly, we have to look for a different software, with which we can open files with the .ONETOC2 extension. Select a different software from our list and install it on your computer. After the software is installed, repeat inspection openings of a .ONETOC2 file. Sometimes you have to repeat the operation several times.
Other instructions
If none of the programs listed by us to work with the .ONETOC2 file has not meet your expectations, you can try searching other websites. But remember to avoid downloading programs "that can open any file". These applications not only have very limited functionality, but may also expose you to expense tens of dollars when purchasing a license.
In the vast majority of cases you will find the program dedicated to support the .ONETOC2 file, or any other file format. In addition, there is a chance that it will be a free program, and its functionality (concerning the .ONETOC2 file) will be extended to the maximum.
It is also good to check
- if the .ONETOC2 file has no errors
- or if it has been copied (or downloaded by the browser) thoroughly
