Notes about the BOX3D 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 BOX3D file type is primarily associated with 'Box Shot 3D' by Applications For Life. Box Shot 3D is a virtual cover renderer based on ray tracing algorithms. Simply put, the box shots you create will look very realistic.
