A .WRZ file represents a gzipped VRML world, where a .WRL 3D scene—built from plain-text instructions describing geometry, materials, textures, lights, and occasional animations—has been compressed tightly for easier sharing, which resulted in the convention of calling such files .WRZ or `.wrl.gz`, and the usual approach is to decompress them with tools like 7-Zip or `gzip` to obtain a .WRL file that VRML-supporting viewers can load, with textures appearing correctly only if their referenced image files stay in the proper 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 email rule export files, 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 open 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 hex signature 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.

Exploring a VRML "world" (the .WRL you get from unpacking a .WRZ) shows a scene graph of typed nodes describing visuals and user movement, with Transform/Group constructs managing transform hierarchies, Shape nodes merging geometry such as Sphere with Material/ImageTexture appearance, and standard world components including Viewpoint cameras, NavigationInfo behavior settings, and bindable environment nodes like Background, optional Fog, and Sound.

VRML’s interactivity uses Sensor nodes like event sensors to send events, animations build on TimeSensor plus the Position/Orientation/Color/Scalar interpolators that provide time-based outputs, and ROUTE links connect everything, while complex behaviors rely on Script nodes with VRMLScript/JavaScript or occasional Java, and Anchor nodes allow hyperlink-like navigation, with the specification distinguishing transform-affected nodes from non-spatial ones such as interpolators, NavigationInfo, TimeSensor, and Script, giving the world the character of a small interactive program rather than a simple 3D model.

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—compressed with 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 the bytes 1F 8B helps confirm it’s truly gzipped VRML.
