- 读取文件夹
- 判断文件夹存在及创建
读取文件夹
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24
| #include <iostream> #include <filesystem>
int main() { std::filesystem::path dir("D:\\dir"); std::filesystem::directory_iterator list(dir);
try { for (auto& file : list) { std::cout << file << " "; std::cout << std::filesystem::file_size(file.path()) << std::endl; } } catch (const std::exception& e) { std::cout << e.what() << std::endl; }
return 0; }

判断文件夹存在及创建
std::filesystem::create_directory
不递归创建,std::filesystem::create_directories
递归创建
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21
| #include <iostream> #include <filesystem>
int main() { std::filesystem::path dir("D:\\dir\\dir1\\dir2"); if (!std::filesystem::exists(dir)) { if (std::filesystem::create_directories(dir)) { std::cout << "success" << std::endl; } else { std::cerr << "failure" << std::endl; } }
return 0; }

还可以创建一些软硬链接:
