Notes about the JST 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 JST 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.
