C++文件管理系统

好的，C++ 文件管理系统可以包含以下功能：

1. 文件的创建、复制、移动、重命名、删除等操作。
2. 目录的创建、复制、移动、重命名、删除等操作。
3. 文件及目录的查找功能。
4. 文件和目录的属性查询功能。
5. 文件和目录的权限管理功能。

以下是一个简单的 C++ 文件管理系统示例代码：

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

namespace fs = std::filesystem;

void create_file(std::string filename) {

        std::cout << "Error creating file!" << std::endl;
    }
    file.close();
}

void copy_file(std::string source, std::string destination) {
    if (fs::copy_file(source, destination)) {
        std::cout << "File copied successfully!" << std::endl;
    } else {
        std::cout << "Error copying file!" << std::endl;
    }
}

void move_file(std::string source, std::string destination) {
