A .WRZ file functions as a compressed VRML world, meaning a .WRL 3D scene—containing text-based definitions for models, materials, textures, lighting, and even simple interactivity—has been reduced using gzip because VRML’s text nature compresses extremely well, leading many systems to label such files as .WRZ or `.wrl.gz`, and to open one you usually extract it using a gzip-capable tool to reveal a .WRL file that VRML/X3D viewers can display, assuming texture files remain in their correct relative directories.
A quick way to verify a real gzip file is to check whether it starts with the signature bytes 1F 8B, which strongly indicates a compressed stream consistent with WRZ being a gzipped WRL, and a frequent confusion comes from mixing WRZ with RWZ, since .RWZ is tied to Outlook’s Rules Wizard rather than 3D content, meaning a file from email migration may be RWZ, while something from a 3D or CAD workflow is more likely a true WRZ.
A .WRZ being called a "Compressed VRML World" means the file is just a VRML world—commonly stored as .WRL, where the extension means *world*—that’s been shrunk using gzip for easier storage or earlier web transfer, as VRML’s text-based scene description (objects, textures, lighting, cameras, and sometimes animations) compresses extremely well, resulting in conventions like naming such files .wrl.gz or .wrz.
Practically, the label "compressed VRML world" is your cue to treat 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 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—IndexedFaceSet—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.

In VRML, interactivity stems from Sensor nodes such as ProximitySensor that emit events, animations come from TimeSensor and multiple interpolators that generate timed value changes, and ROUTEs wire eventOuts to eventIns, while script nodes using VRMLscript/Javascript (and sometimes Java) add advanced behavior, with Anchor nodes enabling jumps to other worlds or viewpoints, and because VRML separates spatial transform nodes from non-spatial elements like interpolators, NavigationInfo, TimeSensor, and script, the result behaves like a lightweight interactive application rather than a static mesh.
What "Compressed VRML World" means for a .WRZ file is that WRZ isn’t its own 3D format but simply a regular VRML scene file—usually .WRL—packed via gzip to reduce size back when web bandwidth was tight, so the content is still VRML text describing shapes, lights, textures, viewpoints, navigation, and simple interactivity, just stored inside gzip and labeled .wrz or .wrl.gz, a convention noted by sources like the Library of Congress, which is why tools like 7-Zip/gzip open it and why checking for the gzip signature 1F 8B helps confirm it’s truly gzipped VRML.
