Open Source Go File Compression Software

Introducing Archiver 4.0 - a cross-platform, multi-format archive utility and Go library. A powerful and flexible library meets an elegant CLI in this generic replacement for several platform-specific or format-specific archive utilities. The core library APIs work pretty well but the command has not been implemented yet, nor have most automated tests. If you need the arc command, stick with v3 for now. Create and extract archive files. Walk or traverse into archive files. Extract only specific files from archives. Insert (append) into .tar files. Numerous archive and compression formats supported. Extensible (add more formats just by registering them) Cross-platform, static binary. Pure Go (no cgo). Multithreaded Gzip. Adjust compression levels. Automatically add compressed files to zip archives without re-compressing Open password-protected RAR archives.
