A high-performance, multithreaded file-system analyzer written in modern C++17. Built to handle massive directories efficiently while providing clean, structured output.
🔍 Recursive directory scanning via std::filesystem
⚡ Multithreaded processing using a worker-thread queue
🔐 Thread-safe aggregation with mutexes + condition variables
