The ONETOC2 file may be unusually small compared to the original file. Usually this applies to ONETOC2 files downloaded from the Internet in case the download did not finish properly. The file should be downloaded again, making sure that the process has finished correctly.
The most common cause here is computer viruses. Perform a virus scan using available and up-to-date anti-virus software. Alternatively, you can use the scanners available online. For the best results, we will scan the entire operating system, not just our ONETOC2 file. As a result of the scan, sometimes it is not possible to recover ONETOC2 files, which are deleted if there is a backup of this file, then after restoring it, it must also be scanned.
A typical compatibility error - the program does not support the older version of the ONETOC2 file. On their websites, developers usually offer free solutions to such problems, e.g. in the form of a conversion program or an older version of the program.

When reading, a message appears that the file was encrypted or corrupted. The encrypted file ONETOC2 except for the special designation, works normally, but only on the device where it was encrypted, before transferring it to another machine, decryption is required.
Some of the system directories are excluded from modification. 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 ONETOC2 file to another location.
This can happen on a file that does not support multiple access. In this case, the ONETOC2 file is blocked by the first application to open it. Just close unnecessary programs. If the error persists after closing other programs, wait for a while. However, some background programs may block the ONETOC2 file while scanning. If nothing helps, please reset the device.
