Opening JAD files

Did your computer fail to open a JAD file? We explain what JAD files are and recommend software that we know can open or convert your JAD files.

What is a JAD file?

JAD stands for Java Application Descriptor file. This particular file extension was developed by Sun Microsystems. Files with the .jad extension are descriptor files that are commonly used to describe the contents of a MIDlet.

MIDlet files are created for the Java ME virtual machine. MIDlets are commonly used to package applications and games that have been created for cell phones and other mobile devices. For the MIDlet application to run properly, it must have both a .jar and .jad file associated with it. The .jar file contains the actual application data and the .jad file contains the technical information needed to operate the MIDlet program.

Try a universal file viewer

In addition to the products listed above, I would suggest that you try a universal file viewer like Free File Viewer. It can open over 200 different types of files - and very likely yours too! Download Free File Viewer.
