C++ File Compressor

A file compressor written in C++.

This application provides lossless compression and decompression for arbitrary binary files through the command-line interface.

Features

• Lossless compression
• Binary-safe processing
• Custom .rle file format
• Command-line interface
• Cross-platform (Linux, macOS, Windows with MinGW)
• Modular design for future algorithm expansion
• File format validation
• Future format versioning
• Corruption detection

Supported File Types ( for now )

The compressor operates on raw byte streams and can process:

• .txt
• .bmp
• .raw
• .bin
• .csv
• .log
• Any arbitrary binary file

Compression Technique

1. Run-Length Encoding (RLE)

The implementation uses byte-level RLE encoding.

Repeated byte sequences are stored in the format:

[count][byte]

Usage

Compress

cpp-compress -c input_file output_file.rle

Decompress

cpp-compress -d input_file.rle output_file

Future Extensions

Future additional compression techniques, will be:

• Huffman Coding
• LZ77 / LZ78
• LZW
