Notes about the X3DBZ 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 X3DBZ file type is primarily associated with 'X3D' by Web3D Consortium. X3D is a royalty-free open standards file format and run-time architecture to represent and communicate 3D scenes and objects using XML.
