Notes about the JUP file extension:
To open this file type, a required software must be installed. Without it you only see a Windows message "The following file cannot be opened
" (Windows 7) or "How do you want to open this file?
" (Windows 10) if you double-click the file. There click on "More apps"
and choose a suitable software to view such files on your PC or from email attachments.
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.
