A .WRZ file is widely recognized as a gzip-compressed VRML world, effectively a .WRL text-based 3D environment—holding geometry, textures, lighting, cameras, and sometimes interactive features—that has been shrunk 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.
A simple check is seeing whether the file begins with 1F 8B, which is typical of gzip-compressed data and supports the idea that WRZ is a gzipped WRL, and people often mix it up with RWZ, a format associated with email rule exports, so a file from an email setup is probably RWZ, while one from a 3D workflow is almost certainly WRZ.
When someone says a .WRZ is a “Compressed VRML World,” they mean that a standard VRML scene file—usually .WRL, literally short for *world*—has been gzipped to reduce space, since VRML uses structured text to describe full 3D scenes like geometry, materials, textures, lights, viewpoints, and basic behaviors, and because text compresses so effectively, the community adopted .wrl.

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.
Inside the VRML “world” (the .WRL produced after you decompress a .WRZ) you’ll find a typed scene graph covering both scene content and navigation, starting with Transform/Group nodes that define position, rotation, and scale, then Shape nodes that mix geometry—Box—with appearance through Material and ImageTexture, as well as world-level nodes like Viewpoint, NavigationInfo, Background, Fog, or Sound.
VRML’s interactivity uses Sensor nodes like TouchSensor 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.
Calling a .WRZ a “Compressed VRML World” means the file isn’t a unique format but a standard VRML world (.WRL) stored as gzip to shrink download/storage size from the early web-3D period, leaving the VRML text intact—shapes, textures, lights, viewpoints, navigation, and simple behaviors—just packaged in gzip and signaled with .wrz or .wrl.gz, as noted by references like the Library of Congress, which is why 7-Zip/gzip opens it and why identifying the 1F 8B bytes helps confirm it’s really gzipped VRML.
