A .WRZ file is basically a gzip-compressed VRML scene, where a .WRL world file—containing text-based 3D data such as shapes, materials, lights, cameras, and occasional animations—has been reduced in size because VRML compresses extremely well, leading to the convention of naming these archives .WRZ or `.wrl.gz`, and the usual method of opening them is to extract with something like 7-Zip or `gzip` to produce a .WRL that VRML/X3D tools can read, provided any texture images remain in the correct relative paths.
A straightforward check is verifying whether the file starts with the hex prefix 1F 8B, a strong sign of gzip compression matching the WRZ format, and a common misunderstanding is mixing it up with RWZ, which belongs to Outlook Rules Wizard exports, so if the file came from email migration it may be RWZ, whereas anything from a 3D or CAD workflow is usually a true WRZ.
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 gzipped 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 speaking, calling it a "compressed VRML world" tells you to open the file like a gzip stream first so it can expand into a .WRL readable by VRML/X3D-compatible tools, and one easy technical check is whether the file begins with the gzip signature that 1F 8B magic, which strongly indicates you’re dealing with a real gzipped VRML file and not a different format that only looks similar by extension.
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—Sphere—with appearance through Material and ImageTexture, as well as world-level nodes like Viewpoint, NavigationInfo, Background, Fog, or Sound.
A VRML world handles interaction through Sensor nodes such as TouchSensor 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.

best app to open WRZ files, it is possible to email us in our own website. A .WRZ being a "Compressed VRML World" means WRZ is just a VRML .WRL file
compressed with gzip for smaller transfers, keeping VRML’s text-based description of meshes, textures, lighting, viewpoints, navigation settings, and simple interactions intact, but delivered in gzip form and named .wrz or .wrl.gz as noted by the Library of Congress; this is why decompression tools like 7-Zip/gzip open it easily, and why the gzip magic bytes 1F 8B help confirm it’s authentic gzipped VRML rather than an unrelated format.
