How to open NUMBERS-TEF file?

The first thing you should do is just "doubleclick" on the NUMBERS-TEF 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 Apple Numbers

Programs to open NUMBERS-TEF file
Remember to download programs supporting NUMBERS-TEF files only from verified and safe sources. We suggest using the websites of software developers.
Step 2. Create association of Apple Numbers with NUMBERS-TEF files
If the application is or has been freshly installed, but the NUMBERS-TEF file still does not use the Apple Numbers program, it means no association. This option is available from the level of Properties of a specific file available in the context menu. Information about the file and the program that the file is associated with are available here. Changes can be made using the "Change" button. If there is no software on the list, simply select "Browse" and manually select the directory where the application is installed. Checking the "Always use the selected program ..." box will permanently associate the NUMBERS-TEF file with the Apple Numbers program.
Step 3. Update Apple Numbers to the latest version
If, despite the association of the Apple Numbers program with the Numbers ICloud Document file, the file still does not open, check the program version and possibly update it to the newest version.
Step 4. Check for the following problems with the NUMBERS-TEF file
The problem may also be with the file itself if the above steps don't work. File problems can be divided into the following:
Very often, the file may be size 0 or incomplete. This suggests truncating the NUMBERS-TEF file contents when downloading or copying. Downloading the file again should fix the problem.
The most common cause here is computer viruses. A quick virus scan using an up-to-date antivirus program should clear up any doubts. Some antivirus vendors also provide free online scanners. For the best results, we will scan the entire operating system, not just our NUMBERS-TEF file. Sometimes virus-infected NUMBERS-TEF files cannot be recovered, so make a backup in advance.
A typical compatibility error - the program does not support the older version of the NUMBERS-TEF 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.
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 NUMBERS-TEF file corruption.
The program can also signal the fact of encryption. The encrypted NUMBERS-TEF files cannot be played on other computers than the one on which they were encrypted, they must be decrypted before using on another device.
Some operating systems do not allow file operations in certain locations, eg in system directories or directly on the system drive. 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 NUMBERS-TEF file to another location.
This problem only occurs with more complex files. In this case, the NUMBERS-TEF file is blocked by the first application to open it. Running programs (including those in the background) should be verified. If the error persists after closing other programs, wait for a while. Antivirus programs or a backup being made may lock the file for a while without the user's knowledge. If this does not work either, restart the device.
