计算C++中嵌套目录中文件的块大小

#include <iostream>
#include <fstream>
#include <filesystem>

namespace fs = std::filesystem;

// 递归计算目录中文件的块大小
uintmax_t calculateBlockSize(const fs::path& directory) {
    uintmax_t totalSize = 0;

    for (const auto& entry : fs::recursive_directory_iterator(directory)) {
        if (entry.is_regular_file()) {
            std::ifstream file(entry.path(), std::ios::binary | std::ios::ate);
            totalSize += file.tellg(); // 获取文件大小
        }
    }

    return totalSize;
}

int main() {
    fs::path directory = "your_directory_path";
    uintmax_t blockSize = calculateBlockSize(directory);

    std::cout << "嵌套目录中文件的块大小为: " << blockSize << " bytes" << std::endl;

    return 0;
