Why convert G3FC to TAR?
G3FC packs files with Zstandard compression, encryption, and error correction, while .tar is a plain uncompressed bundle used widely on Linux and in build pipelines. People convert when they need a portable, tool-agnostic container that any Unix system can read without the G3FC program.
How to convert G3FC to TAR
g3fc CLI (extract) OPEN-SOURCE
Run g3fc extract archive.g3fc -o ./output_dir (add -p "password" for encrypted archives) to restore the original files.
tar (repack) FREE
Bundle the extracted folder with tar -cf output.tar ./output_dir; add --zstd to also compress it.
tar on macOS/Windows FREE
The bundled tar (macOS, and Windows 10+) runs the same tar -cf output.tar ./output_dir after extraction.
About these formats
A .g3fc file is a Generation 3 File Container archive, an open-source format that bundles one or more files using Zstandard compression, with optional AES-256-GCM encryption and…

Tape Archive
A TAR file (also called a tarball) bundles files and folders into one archive but does not compress them. That is why you almost always see it as .tar.gz or .tgz, with gzip added on top. On…

Frequently asked questions
Why is my .tar bigger than the .g3fc?
.tar does not compress; it only concatenates files. G3FC compresses with Zstd, so it is smaller.Can I compress the tar too?
tar --zstd -cf output.tar.zst ./output_dir or pipe through gzip for .tar.gz.Does tar keep folder structure?
tar preserves the directory tree of the files you extracted from the G3FC archive.Which tar version do I need for zstd?
--zstd flag directly.
