Notes about the JUP file extension:
Incorrect file associations could be the result of underlying issues within your PC system. As such it is highly recommended to scan your PC for invalid registry entries, unused processes and other unfavourable system settings to identify slowdown issues.
The JUP file type is primarily associated with 'Code Crusader' by New Planet Software. Code Crusader is a graphical Integrated Development Environment (IDE) designed to integrate the tasks of working with source files, compiling, and debugging.
