How to open JSS file?

An often recurring problem with JACOsub Subtitle Format is that JSS is not associated with the correct program file. This causes the file JSS to open by system applications not designed for this purpose, or to display a message that there is no associated program. How to solve such a problem?

The first thing you should do is just "doubleclick" on the JSS 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 VLC media player

An often overlooked issue is to make sure that VLC media player is installed on the computer. To do this, enter the name VLC media player into the system search engine. If it is not, installation may solve the problem, as most applications create file associations during installation. Below is a list of programs that support the file JSS.

Step 2. Create association of VLC media player with JSS files

If the application is or has been freshly installed, but the JSS file still does not use the VLC media player program, it means no association. This option is available from the level of Properties of a specific file available in the context menu. The displayed window will contain information about the program that supports this type of file. 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 JSS file with the VLC media player program.

Step 3. Update VLC media player to the latest version

If, however, after binding VLC media player with JACOsub Subtitle Format there were still problems, you should update the program to the latest version. In this case, use the VideoLAN Project Team website or update the program from the application.

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

If the above steps do not help, you can assume that the file itself is not correct. File problems can be divided into the following:

The affected file may be 0 KB or smaller than expected. This is most often caused by a problem while downloading the JSS file. The only repair option is to download the file again.
The computer may have fallen victim to a computer virus or hacker. 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 JSS file that we want to open. As a result of the scan, sometimes it is not possible to recover JSS files, which are deleted if there is a backup of this file, then after restoring it, it must also be scanned.
This can happen especially when the program is dynamically developed and the structure of the JSS files changes over time. 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 this. The repair method must be adapted to the type of file and damage. Some programs offer the option of recovering data from damaged JSS files. The easiest way is to restore the file from a backup, if there is one, or contact JACOsub
The program can also signal the fact of encryption. The encrypted JSS 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.
Some of the system directories are excluded from modification. The problem is only writing to the file, not reading it. Copying the JSS file to another location will fix the problem.
This can happen on a file that does not support multiple access. You may find that another program you are using is preventing you from working with the file. Closing other programs should help. Sometimes you have to wait for the session to the file JSS 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.
