JAD file extension is used by Java Application Descriptor files. These files contain metadata about java mobile edition applications (MIDlets) that can be downloaded from the Internet. Usually these applications are intended to be used on mobile phones. The applications themselves are contained in .File extension JAR archives.
JAD files contain the following tags:
MIDlet-1 - contains information about application name, icon and startup class
MIDlet-Jar-Size - number of bytes in the application JAR file
MIDlet-Jar-URL - Internet address where application archive can be downloaded
MIDlet-Name - redundant tag used to store application name only
MIDlet-Vendor - information about the company that authored the MIDlet
MIDlet-Version - application version number
MicroEdition-Configuration - information about CLDC version required to run particular MIDlet
MicroEdition-Profile - information about MIDP version required to run particular MIDlet
If you need to open JAD file and view what is inside you can just rename it to TXT and view it in any text editor.
