How to open J2K file?

An often recurring problem with JPEG 2000 Image is that J2K is not associated with the correct program file. This is manifested by the fact that J2K files open in unusual applications or do not have an assigned program. How to solve such a problem?

The first thing you should do is just "doubleclick" on the J2K 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 GraphicConverter

An often overlooked issue is to make sure that GraphicConverter is installed on the computer. To do this, enter the name GraphicConverter into the system search engine. If we do not have this program, it is worth installing it, as it will help you automatically associate the file J2K with GraphicConverter. Below you will find a list of applications that support J2K files.

Step 2. Create association of GraphicConverter with J2K files

If the application is or has been freshly installed, but the J2K file still does not use the GraphicConverter 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. Changes can be made using the "Change" button. The program should be visible in the window, otherwise it should be selected manually using the "Browse" button and the program installation directory should be indicated. However, it is important to check the "Always use the selected program ..." box, this will allow you to permanently associate the J2K file with the GraphicConverter application.

Step 3. Update GraphicConverter to the latest version

If, however, after binding GraphicConverter with JPEG 2000 Image there were still problems, you should update the program to the latest version.

Step 4. Check for the following problems with the J2K file

If the above steps do not help, you can assume that the file itself is not correct. The most common file problems are:

The J2K file may be unusually small compared to the original file. Usually this applies to J2K 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. A quick virus scan using an up-to-date antivirus program should clear up any doubts. Some antivirus vendors also provide free online scanners. However, it is important to scan the entire system, not only the file J2K or the program directory. However, remember that not every infected J2K file can be recovered, so it is important to take care of regular backups.
This can happen especially when the program is dynamically developed and the structure of the J2K 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 this. The repair method must be adapted to the type of file and damage. Some programs offer the ability to automatically repair J2K file corruption.
The program indicates that the file is encrypted or corrupted. The encrypted J2K 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 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 J2K file to another location.
This problem only occurs with more complex files. Some file types can only be opened in one program at a time. Just close unnecessary programs. Sometimes you have to wait for the session to the file J2K to close. 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.
