Notes about the HZX 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 HZX file type is primarily associated with 'CrossWorks' by Rowley Associates Limited. CrossWorks is a complete development solution for MSP430 projects -- from initial design through final production. The linked executable is produced by the linker.
