STL. filesystem. Is there a way to reverse iterate over a directory?

Question

C++ / C#

Please do not confuse with recursive iteration. I need to somehow get fs::directory_entryfrom the end to the beginning. There are no methods operator--()or decrement()the class fs::directory_iterator, there are no traits for the constructor either. The type class is fs::reverse_directory_iteratormissing. So is there a way?

Answer 1

In general, the most normal way is to create std::set<fs::path>and fill it with content, and then use a reverse iterator std::set.

std::set<fs::path> file_paths;

for (const auto& dir_entry : fs::directory_iterator{"path/to/directory"})
    file_paths.insert(dir_entry.path());

auto iter = file_paths.rbegin();
auto end = file_paths.rend();
