Multi-format archive and compression library

Multi-format archive and compression library

The libarchive library features:

  • Support for a variety of archive and compression formats.
  • Robust automatic format detection, including archive/compression combinations such as tar.gz.
  • Zero-copy internal architecture for high performance.
  • Streaming architecture eliminates all limits on size of archive, limits on entry sizes depend on particular formats.
  • Carefully factored code to minimize bloat when programs are statically linked.
  • Growing test suite to verify correctness of new ports.
  • Works on most POSIX-like systems (including FreeBSD, Linux, Solaris, etc.)
  • Supports Windows, including Cygwin, MinGW, and Visual Studio.
