How to open ONETMP file?

The most common problem when using Microsoft OneNote Temporary is that a specific ONETMP is not associated with the program. This causes the file ONETMP to open by system applications not designed for this purpose, or to display a message that there is no associated program. This problem can be easily remedied.

The first thing you should do is just "doubleclick" on the ONETMP file icon you want to open. If the operating system has an appropriate application to support it and there is also an association between the file and the program, the file should be opened.

Step 1. Install Microsoft OneNote

In this case, you should first verify that the Microsoft OneNote application is installed on the computer. The easiest method is to use the system search engine by entering the program name Microsoft OneNote in it. If we do not have this program, it is worth installing it, as it will help you automatically associate the file ONETMP with Microsoft OneNote. Later in this article you will find a list of programs that can open ONETMP files.

Programs to open ONETMP file

Remember to download programs supporting ONETMP files only from verified and safe sources. We suggest using the websites of software developers.

Step 2. Create association of Microsoft OneNote with ONETMP files

However, it may happen that the application itself does not cause the ONETMP file to open in the Microsoft OneNote application, but you can set it manually. 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. Changes can be made using the "Change" button. It may happen that in the next window there will be no appropriate program - however, this can be corrected with the "Browse" option where you should manually indicate the program location. Checking the "Always use the selected program ..." box will permanently associate the ONETMP file with the Microsoft OneNote program.

Step 3. Update Microsoft OneNote to the latest version

If, however, after binding Microsoft OneNote with Microsoft OneNote Temporary there were still problems, you should update the program to the latest version. In this case, use the Microsoft Corporation website or update the program from the application.

Step 4. Check for the following problems with the ONETMP file

Of course, it may happen that despite the above steps, the file still does not work. The most common file problems are:

The affected file may be 0 KB or smaller than expected. Usually this applies to ONETMP files downloaded from the Internet in case the download did not finish properly. Downloading the file again should fix the problem.
The operating system may be infected with a computer virus. A virus scan using an up-to-date antivirus program should fix the problem. Some antivirus vendors also provide free online scanners. The scan should cover the entire computer, not only the ONETMP file that we want to open. Sometimes virus-infected ONETMP files cannot be recovered, so make a backup in advance.
A typical compatibility error - the program does not support the older version of the ONETMP file. These problems are known and are often very easy to fix using the software developers's website.
The file may be corrupted in a number of ways. The repair method must be adapted to the type of file and damage. Some programs offer the ability to automatically repair ONETMP file corruption. The easiest way to restore the file is from a backup or by contacting Microsoft Corporation, but this one can be expensive. Not all damage can be reversed.
The program can also signal the fact of encryption. The encrypted ONETMP files can be used by the device on which they were encrypted, on any other device it is required to have the appropriate cryptographic key and decrypt the file before its recovery.
The operating system protects files in some locations (e.g. the root of the system partition) against unauthorized access. These directories are write-protected to them and it's very hard to fix this problem. It is best to move ONETMP to a different directory.
This problem only occurs with 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 ONETMP file while scanning. If the problem persists, restart the machine.
