Professional File Compressor v2.0 - Delivering enterprise-grade compression solutions with exceptional performance and reliability.

Advanced File Compressor

Universal Compressor CLI (New)

• Binary: bin/universal_comp.exe
• Purpose: Robust, lossless single-file compressor/decompressor using a simple COMP container with CRC32 verification.
• Algorithms:
  • STORE (always available): fast, no compression, guarantees bit-perfect roundtrip.
  • ZLIB (optional): enable by building with -DUSE_ZLIB and linking -lz.

Features

• Writes a minimal COMP header containing magic, version, algorithm, sizes, and CRC32.
• Restores original file extension from the input path.
• Verifies decompressed data against stored CRC32 for bit-perfect integrity.

Usage

• Compress: universal_comp.exe -c data\file.txt
• Decompress: universal_comp.exe -d data\file.txt.comp
• Use zlib (if available): universal_comp.exe --zlib -c data\file.txt

Build (without make)

• Windows (PowerShell):
  • gcc -O2 -Iinclude src/universal_cli.c src/comp_container.c src/zlib_adapter.c src/crc32.c src/logger.c src/logger_shim.c -o bin/universal_comp.exe
• With zlib:
  • gcc -O2 -DUSE_ZLIB -Iinclude src/universal_cli.c src/comp_container.c src/zlib_adapter.c src/crc32.c src/logger.c src/logger_shim.c -o bin/universal_comp.exe -lz
• With vendored miniz:
  • gcc -O2 -DUSE_MINIZ -Iinclude -Ithird_party/miniz src/universal_cli.c src/comp_container.c src/zlib_adapter.c src/crc32.c src/logger.c src/logger_shim.c third_party/miniz/miniz.c -o bin/universal_comp.exe

Build (make, optional)

• make ZLIB_ENABLED=1 compiles with zlib and produces bin/universal_comp.exe.
• make MINIZ_ENABLED=1 compiles with vendored miniz and produces bin/universal_comp.exe.

Notes

• If zlib is not available, the tool falls back to STORE mode (copy) while still providing CRC32 verification.
• Output filenames on decompression strip .comp and use the original extension stored in the header.

Installing zlib (optional)

• Windows (MSYS2/mingw): install zlib via pacman -S mingw-w64-x86_64-zlib, then build with -DUSE_ZLIB -lz.
• Windows (vcpkg/MSVC): vcpkg install zlib and link zlib.lib, compile with /DUSE_ZLIB.
• Linux: sudo apt-get install zlib1g-dev and build with -DUSE_ZLIB -lz.
