What are JNLP files and how to open them

Are you having problems opening a JNLP file or are you simply curious about its contents? We're here to explain the properties of these files and provide you with software that can open or handle your JNLP files.

What is a JNLP file?

A .JNLP file is a Java Network Launching Protocol for Java Web Start file.

JNLP is an acronym for Java Network Launching Protocol. Java is a programming language that uses the JNLP file format to launch and manage various Java applications over a network or the Internet. The JNLP files are saved in the XML file format and contain information about an application written in Java, e.g., where to download it and how to launch it.

Unlike typical web applets, JNLP files are not run within a user's Web browser. These files are actually downloaded onto a user's computer and are then run as regular Java applications. The files are used only for stand-alone applications.
