Box - Open Standard Archive Format

⚠️	Box is under active development. Do not expect compatibility between versions until v1.0.

The .box file format and related tooling is designed to be a modern successor to formats such as .zip and .7z, removing several painpoints and introducing modern features and expectations:

Features

🌉	Cross-platform path support, with relative paths only and platform-agnostic separators
🌐	UTF-8 only, Unicode normalised path names and string data
🔍	FST-based indexing for extremely fast path lookups
👩‍🚀	Extensible with space-efficient attributes in key-value pairs for records and whole archives
↔️	Configurable optional byte-alignment of files to enable easy memory mapping
💽	Inode-based metadata for tree-based structuring, mapping closely to how filesystems work
📁	Support for directories, files and links
🗜️	Multiple compression methods within a single archive
🖥️	A truly cross-platform command line tool
📜	Well-defined, open specification of file format (due before v1.0)
