How to open NOS file?

An often recurring problem with JDOS System is that NOS is not associated with the correct program file. This causes the file NOS 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 NOS 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 JNOS

An often overlooked issue is to make sure that JNOS is installed on the computer. To do this, enter the name JNOS into the system search engine. If it is not, installation may solve the problem, as most applications create file associations during installation. Below you will find a list of applications that support NOS files.

Programs to open NOS file

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

Step 2. Create association of JNOS with NOS files

If the application is or has been freshly installed, but the NOS file still does not use the JNOS 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 displayed window will contain information about the program that supports this type of file. Using the "Change" button we can set the program to handle this type. 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. However, it is important to check the "Always use the selected program ..." box, this will allow you to permanently associate the NOS file with the JNOS application.

Step 3. Update JNOS to the latest version

If, despite the association of the JNOS program with the JDOS System 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 NOS file

The problem may also be with the file itself if the above steps don't work. This could be due to the file itself, the cleanest issues are:

Very often, the file may be size 0 or incomplete. This is most often caused by a problem while downloading the NOS file. Downloading the file again should fix the problem.
The most common cause here is computer viruses. Perform a virus scan using available and up-to-date anti-virus software. Some antivirus vendors also provide free online scanners. The scan should cover the entire computer, not only the NOS file that we want to open. Sometimes virus-infected NOS files cannot be recovered, so make a backup in advance.
A typical compatibility error - the program does not support the older version of the NOS file. Help should be sought from the software developer, as they usually recommend using free file converters or installing an older version of the program.
The file may be corrupted in a number of ways. Repairing is very dependent on the file type. Sometimes the program itself has options to repair the most popular NOS file corruption.
The program indicates that the file is encrypted or corrupted. The encrypted file NOS 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. It is best to move NOS to a different directory.
This problem usually affects more complex files. In this case, the NOS 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. Antivirus programs or a backup being made may lock the file for a while without the user's knowledge. If nothing helps, please reset the device.
