Notes about the MSZ 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 MSZ file type is primarily associated with 'MiSZle' by Mystic Fractal. MiSZle is an interactive program that generates fractal images based on 4X4 matrices, and other fractal types. MiSZle uses the same built-in formulas and quad math as the original DynaMaSZ. Therefore quaternion images may be exported to DynaMaSZ for additional processing by changing the data file extension from MSZ to DSZ.
