Step 2. Create association of Microsoft OneNote with ONETOC files
If the application is or has been freshly installed, but the ONETOC file still does not use the Microsoft OneNote program, it means no association. The association can be created using the drop-down list available by right-clicking on the file and selecting Properties. The window will show, among other things, the type of the file and the information by which the program is used to launch the file. Using the "Change" button we can set the program to handle this type. If there is no software on the list, simply select "Browse" and manually select the directory where the application is installed. However, it is important to check the "Always use the selected program ..." box, this will allow you to permanently associate the ONETOC file with the Microsoft OneNote application.

Some applications allow you to update from the program level, and for others you need to download the installer from the Microsoft Corporation page and install.
Step 4. Check for the following problems with the ONETOC file
If the above steps do not help, you can assume that the file itself is not correct. File problems can be divided into the following:
The ONETOC file may be unusually small compared to the original file. This is most often caused by a problem while downloading the ONETOC file. The file should be downloaded again, making sure that the process has finished correctly.
The computer may have fallen victim to a computer virus or hacker. A quick virus scan using an up-to-date antivirus program should clear up any doubts. If this is not possible, you can use the online scanner. For the best results, we will scan the entire operating system, not just our ONETOC file. Sometimes virus-infected ONETOC files cannot be recovered, so make a backup in advance.
This can happen especially when the program is dynamically developed and the structure of the ONETOC files changes over time. Help should be sought from the software developer, as they usually recommend using free file converters or installing an older version of the program.
There can be many reasons for the failure. Depending on the type of file, it is necessary to repair it accordingly. Sometimes the program itself has options to repair the most popular ONETOC file corruption. The easiest way is to restore the file from a backup, if there is one, or contact Microsoft Corporation
The program indicates that the file is encrypted or corrupted. The encrypted ONETOC files cannot be played on other computers than the one on which they were encrypted, they must be decrypted before using on another device.
The operating system protects files in some locations (e.g. the root of the system partition) against unauthorized access. While there is usually no problem reading such a file, it may not be possible to save it. If possible, you can try to move the ONETOC file to another location.
This problem usually affects more complex files. Some file types can only be opened in one program at a time. Running programs (including those in the background) should be verified. If the error persists after closing other programs, wait for a while. However, some background programs may block the ONETOC file while scanning. If nothing helps, please reset the device.
