What is a JAR file?
JAR (Java ARchive) is a file format based on ZIP that is used to aggregate many Java class files and associated metadata and resources into a single file for distribution. It simplifies deployment of Java applications and libraries.
JAR files can also include executable code and are often used to package Java applets or Java-based programs. Because it’s essentially a ZIP file, it can be opened with many archive tools.
How to open JAR files
JAR files can be opened using archive tools like 7-Zip or WinRAR, or executed with the Java Runtime Environment (JRE) if they contain executable code.
You can also extract or convert JAR files with AnyConv if you're looking to access the contents without running the program.

The file that played music
In the early 2000s, many mobile games and apps were distributed as JAR files - and clever developers discovered they could also bundle MP3s inside. This led to a wave of “music player JARs” that teenagers swapped over Bluetooth, turning a format meant for code into an underground way to share songs.
