Subject: Boost::Filesystem - How to iterate, through the whole drive
To: <boost-users@lists.boost.org>

Hey guys, I need iterate over all directories from starting path. If I start iterating from C:\some-dir it works very well, however if I try to iterate from C:\, it doesn't work. How can iterate through the whole drive? Thank you.

Code is here: https://pastebin.com/mpsKJxH2. The problem I experience is commented right in the code section (line 1, 13 and 25).

This works for me, either with boost-1.68 (not that I think that matters) or the STL-VC-15.9.1 (/std:c++17):

#include <iostream>
#include <boost/filesystem.hpp>

namespace fs = boost::filesystem;

int main ( ) {
    for ( auto & p : fs::recursive_directory_iterator ( "d:\\" ) ) {
        std::cout << p.path ( ) << '\n';
    }
}

Note that: "The iteration order is unspecified, except that each directory entry is visited only once."
