In case of not knowing, a JAR file is a Java archive package format that might include a Java program within it.
While you can extract JARs with archiving software, you can’t run a pure Java JAR app as you would with other programs in Windows.
Since that’s the case, we’ll cover how you can run a pure Java app JAR file in Windows.
How are JAR files helping you?
A JAR file allows Java runtimes to enclose an entire application, together with its classes and resources, in a single source.
Moreover, the elements inside a JAR file can be compressed, and that translates by shorter download times but also less space allocated on your drive.
In fewer words, JARs are more sophisticated archives that work in a Java environment on your PC.
How can I run a JAR file on Windows 10?
1. Add Java to Windows

java -version




The crucial thing you need upfront is to have Java installed. Without it, Java apps aren’t going to run in Windows.
2. Use Java (TM) Platform SE binary



3. Download a JAR file opener




You can open JAR files with a lot of apps out there but we strongly recommend File Viewer Plus because it can open and display over 300 different file types.
The new updated version has a plethora of features that will save you big time on opening, viewing, or editing files.
Keep in mind that the app supports the most popular text, audio, or video file type, as well as archive, source code, or web files.
4. Run a JAR file from the Windows Command Prompt

java -jar c:\pathtojarfile.jar

That will open the executable JAR file so long as it contains a manifest file to specify the application’s entry point (the developers should have already included that in the archive.)
If you develop your own Java programs, you’ll need to convert the JAR to an executable format.
The command-lie app is crucial for debugging and installing apps but if it doesn’t work, learn how you can fix Command Prompt in Windows.
5. Add a third-party JAR executor to Windows


There are also executor programs for Windows like JARX that enable you to run JAR files the same as any other program.
How to get a JAR file for your favorite app?
There are lots of websites that offer free JAR versions of any application you can think of and we’re going to provide a simple example for Instagram.



If you’re having trouble or you receive an error, learn what to do if you’re unable to access JarFile on Windows 10.
We hope that our guide helped you with all the information needed to run JAR files in Windows or even convert them if needed.
