go-unixfs is an implementation of Unix-like filesystem utilities built atop an IPLD MerkleDAG, providing a robust framework for file manipulation within the IPFS ecosystem. While this repository is no longer maintained and lacks security updates, it crucially features package subcomponents optimizing file handling, directory operations, importing-exporting processes, and directory sharding via CHAMP HAMT. The high-level package defines the core UnixFS format and assists in file transformation, directory interfacing, and modifications using the DagModifier tool. Users are advised to transition to the maintained version at https://github.com/ipfs/boxo/tree/main/ipld/unixfs, taking advantage of provided documentation and tooling for a seamless migration.
