What is a J file?

J file extension has JAR Archive file type, which is associated with the "compressed files" category.

JAR is a compression tool that has replaced the ARJ file compressor utility with its .ARJ format. Compressed files created by JAR are saved as archives with the .J extension. There is a 16-bit version, and a 32-bit JAR version – the first one is designed for DOS, and the second one for the Windows platform. This format has nothing to do with Java archives that use the .JAR format. 

To learn how you can open the given file, read the information below.
