What is a GBKF file?
A GBKF file is a data file saved in the Generic Binary Keyed Format (GBKF), a compact binary format designed for storing and transmitting structured data. It contains data using a key-value system, where each piece of information is associated with a key and may be grouped into instances or arrays. The GBKF format allows software to read and write complex datasets efficiently, without requiring a fixed schema or text-based format like JSON or XML.
More Information
Rafael Senties Martinelli, the creator of the web-based tool CAD-Viewer.com, developed the GBKF format in 2025 to reduce the amount of data exchanged between CAD-Viewer.com's servers and clients. Martinelli created the first version of GBKF specifically for the CAD-Viewer.com platform, and refactored it into a core specification with extensions to make it more general-purpose. Developers can also adapt the format for other applications, such as databases, messaging systems, or media storage.
How to open a GBKF file
GBKF files are not meant to be opened. Instead, the program, such as CAD-Viewer.com, loads GBKF files in the background.
