A .WRZ file is normally a gzip-compressed VRML world, effectively a .WRL text-based 3D environment—holding geometry, textures, lighting, cameras, and sometimes interactive features—that has been compressed for easier distribution, which is why formats like .WRZ or `.wrl.gz` became common, and the practical way to view it is to extract it with 7-Zip or `gzip` to obtain a .WRL file readable by VRML-compatible viewers, making sure related texture files stay in the expected folders.
One fast way to confirm gzip compression is checking for the header 1F 8B at the beginning, which strongly aligns with WRZ’s role as a gzipped WRL, and many users confuse this with RWZ, a file type used for Outlook Rules Wizard data, so files tied to email management may actually be RWZ, while those from modeling or CAD tools are likely legitimate WRZ files.
The phrase “Compressed VRML World” for a .WRZ indicates that it’s a VRML scene file—typically a .WRL, with “WRL” meaning *world*—that has been compressed with gzip to reduce its footprint, because VRML uses structured text to define entire 3D scenes including geometry, materials, textures, lights, and interactive elements, and this text compresses very efficiently, so the VRML ecosystem commonly labels gzipped VRML as .wrl.gz or .wrz.
Practically, the label “compressed VRML world” is your cue to decompress the file as gzip before anything else, letting you extract a .WRL compatible with VRML/X3D viewers, and a dependable indicator is the presence of the gzip magic bytes the header 1F 8B at the start, strongly confirming it’s a real gzipped VRML file and not another format that happens to share a similar extension pattern.
When you look inside a VRML “world” (the .WRL you obtain once a .WRZ is decompressed), you typically find a node-based scene graph explaining both the visuals and navigation, starting with Transform/Group structures that handle position, rotation, and scale, followed by Shape nodes that join geometry—Extrusion—with appearance details via Material and ImageTexture, plus common world features like Viewpoint cameras, NavigationInfo movement modes, and environment bindings such as Background, Fog, or Sound.
A VRML world handles interaction through Sensor nodes such as other event sensors that fire events, while animations rely on TimeSensor plus the various interpolators (Position/Orientation/Color/Scalar) to produce timed value changes, all linked together via ROUTE connections, and advanced logic is added through Script nodes using VRMLScript/JavaScript or, in some cases, Java, with Anchor nodes enabling hyperlink-style navigation, and VRML distinguishes spatial nodes in the transform tree from non-spatial nodes like interpolators, NavigationInfo, TimeSensor, and Script, giving the world an interactive program-like feel.

The phrase “Compressed VRML World” for .WRZ indicates that WRZ isn’t a separate 3D type but a normal VRML .WRL scene that’s been gzip-packed to make distribution smaller, preserving the VRML text that defines meshes, textures, lights, cameras, navigation, and basic interactivity, wrapped in gzip with typical extensions .wrz or .wrl.gz, a convention cited by the Library of Congress; that’s why tools like 7-Zip/gzip open it, and why checking for gzip’s magic bytes the 1F 8B prefix is a good sanity check.
