How to Open Up a JAR File

A JAR file is a type of file used by Java, a programming language developed by Sun Microsystems and released on the World Wide Web in 1995. JAR files are compressed files (archives) that contain programs written in Java. Opening a JAR file is a quick and easy procedure, but it requires that Java be installed on your computer. Java can be downloaded free of charge from the Web and it installs with a few quick mouse clicks.

Instructions

    • 1

      Open a Web browser, navigate to Java.com and download a free copy of Java. Click on the red "Free Java Download" button to initiate the download. Save the downloaded file to your desktop.

    • 2

      Double-click the Java download on your desktop and follow the on-screen prompts to install Java on your computer.

    • 3

      Locate the JAR file that you want to open – it will have a ".jar" extension at the end of the file name.

    • 4

      Double-click on the JAR file. If the file contains a compressed Java program, it will open and run automatically. Otherwise, continue on to the next step.

    • 5

      Right-click on the JAR file and select "Open" from the context menu. The archived files within will be unpacked. JAR files sometimes contain a collection of several different Java programs. In this case, you can also use a ZIP file compression utility such as WinZip to open the JAR file.
