About CGZ files

A .CGZ file primarily represents two distinct formats: a Linux Drivers Archive or a Cube Map File. In Linux environments, particularly in distributions developed by Red Hat, a .CGZ file is a CPIO archive that has been compressed using GZ (gzip). It is traditionally used to store hardware drivers required during the initial operating system installation phase. Alternatively, it is a compressed 3D level map created by Wouter van Oortmerssen for the Cube or Sauerbraten game engines, storing polygon geometry, entity placements, and lighting data. Both variations of this format present extreme compatibility challenges for the average user. Linux driver archives are essentially double-wrapped files (.CPIO.GZ), making them completely inaccessible natively on Windows or macOS. Users often find themselves frustrated when standard archiving tools fail to dig past the first compression layer. Cube map files are closed and highly proprietary; they are useless outside of their specific game engines because no mainstream 3D modeling software recognizes their internal architecture. Standard online converters routinely fail to process them due to the lack of specific engine rendering libraries. Your best course of action is to extract Linux archives into standard ZIP or TAR formats to easily browse the internal configuration files and binaries. For game maps, true conversion to a standard 3D format like OBJ or FBX requires running native export scripts directly inside the Cube engine itself. Our platform can identify the file format, inspect the file, and show internal content. If our analysis detects the standard underlying Linux archive wrapper, extracting the internal files is fast and painless.

Convert.Guru analyzes your CGZ file, detects the exact format, and lets you read the text inside.

The CGZ Converter Story

The history of Convert.Guru began over 25 years ago in California with Tom Simondi’s file-format database. A former contributor to Space Shuttle development and a software pioneer of the 1980s, Simondi established a trusted resource for file type analysis that was even referenced by Microsoft Windows XP. Today, we use modern technology to process and convert thousands of file formats while continually improving our CGZ converter.
