What is a .JAR file?

JAR files are archives that store executable programs or program libraries written in Java. The files can be executed on any operating system with the Java Runtime Environment (JRE) installed. JAR files are compressed archives that contain program resources, which may include CLASS files and a manifest file.

If you want to extract the contents in a Java archive, you can use File Viewer Plus. This capability is helpful if you are looking to view or modify the contents in a JAR archive.
