c++ Boost if .extension() == "" this would mean this file is a folder?

I just want to confirm that this would be a good method to allow me to only work only on folders, as i can see a way to just look for folder rather that files and folders . 

boost::filesystem::directory_iterator iterator(string("."));
for (; iterator != boost::filesystem::directory_iterator(); ++iterator)
{
    if ((iterator->path().extension()) == "") { 
        cout << (iterator->path().stem()) <<   endl; 
    };
}

Files can exist without any extension, so this won't work.

Have a look at boost::filesystem::is_directory.

By the way, Boost.Filesystem library was merged into C++17 standard. So, if your compiler supports C++17, consider using the standard library for filesystem operations.
