unrar-mini

A modernized, sanitized, and extremely minimal RAR extraction engine optimized for QuickView.

Goals

  • Minimal Footprint: Stripped of legacy OS abstractions, multi-threading overhead, and non-essential features.
  • Modern Standards: Compiled using C++20 with strict warning levels (/W4 /WX).
  • High Performance: Optimized for single-file extraction speed with SIMD support (SSE/SSE2/SSSE3/SSE4.1).
  • License Compliant: Fully compliant with the UnRAR license.

Build Requirements

  • Compiler: MSVC (Visual Studio 2022+), GCC 11+, or Clang 13+.
  • Standard: C++20.
  • Build System: CMake 3.20+.

Features

  • Full support for RAR 5.0 and RAR 3.0 archive formats.
  • Simplified system abstractions (no Mark-of-the-Web, no legacy NT checks).
  • Static library build for easy integration.

Usage

Add this repository as a submodule or include it directly in your CMake project:

add_subdirectory(unrar-mini)
target_link_libraries(your_app PRIVATE unrar-mini)

License

Based on the UnRAR source by Alexander Roshal. Use of this source is governed by the UnRAR License (see LICENSE for details). This code may be used for extraction only.
