<filesystem>

Include the header <filesystem> to define classes and functions for the manipulation of files and directories.

#include <filesystem>

경고

The <filesystem> header is not a C++ standard, although it is being proposed for standardization.If it is adopted as a standard, we will investigate the impact on the interface.
