Jarfix is a free tool that aids with the recapturing of .jar association with the Java Runtime Environment. It allows you to open Java files you usually can’t.
Fixing the problem
The .jar file type is common in many applications; as such, many can hijack the extension and open the wrong file when running a program. Jarfix solves the issue by re-assigning the .jar files to their correct Java Runtime Environment.
The primary use of this application is for developers who need to run the .jar files but are blocked from doing so due to other programs using the extension. However, with knowledge of how Windows works, you can do this without the application.
By default, Jarfix will solve all your file issues without any hassle; however, there are various parameters you can use to customize its behavior. You can set the application to run as administrator with the '/a' command or set an alternative icon for .jar files using '/i'.
You can feed Jarfix with an alternative configurable file by making a second file with the name of that .exe but rename it with the .ini extension instead. With this, you can fully control what action will happen when you open a .jar file. Using '/l' to create a symbolic link between files was recently added.
Any Windows system
The software will work on any computer due to its lightweight design requiring only a single megabyte of space to function. The executable will not break down on operating systems as old as Windows 95 or as new as Windows 10. It has also been kept up to date to work on the latest Java versions.
Safe to use
Jarfix has received the stamp of approval from Softpedia stating that it has no viruses, malware, or adware making it safe to use on your computer. The application will work with any version of Java from the moment you download it.
