#649 [Feature request] G3FC File Format Support

[Lucas Guimarães]

Hello there!
First, thank you for creating and maintaining 7-Zip; it is an invaluable tool for the software community.

I would like to formally request consideration for adding decompression support for a new, modern archive format: G3FC (.g3fc).

G3FC is an open-source file container designed for high performance and security, utilizing modern technologies like Zstandard (Zstd) for compression and AES-256-GCM for authenticated encryption. Adding support for it would allow 7-Zip users to handle these next-generation archives seamlessly.

The entire project is open-source, and all reference implementations (in Rust, C#, Go, and Python) and the full technical specification are publicly available to facilitate implementation.

You can find all the necessary resources at our official GitHub repository:

We believe G3FC's focus on modern standards aligns well with 7-Zip's reputation for supporting a wide range of efficient formats.

Thank you for your time and consideration.
