How to open JPG2 files
If you cannot open the JPG2 file on your computer - there may be several reasons. The first and most important reason (the most common) is the lack of a suitable software that supports JPG2 among those that are installed on your device.

- Corruption of a JPG2 file which is being opened
- Incorrect links to the JPG2 file in registry entries.

If you are sure that all of these reasons do not exist in your case (or have already been eliminated), the JPG2 file should operate with your programs without any problem. If the problem with the JPG2 file has not been solved, it may be due to the fact that in this case there is also another rare problem with the JPG2 file.

How to associate the file with an installed software?
If you want to associate a file with a new program (e.g. my-file.JPG2) you have two ways to do it. The first and the easiest one is to right-click on the selected JPG2 file. From the drop-down menu select "Choose default program", then click "Browse" and find the desired program. The whole operation must be confirmed by clicking OK. The second and more difficult to do is associate the JPG2 file extension to the corresponding software in the Windows Registry.
Is there one way to open unknown files?
Many files contain only simple text data. It is possible that while opening unknown files (e.g. JPG2) with a simple text editor like Windows Notepad will allow us to see some of the data encoded in the file. This method allows you to preview the contents of many files, but probably not in such a structure as a program dedicated to support them.
