The following example shows you how recursively get and list all folders.

C++ example

#include <iostream>
#include <map>
#include <string>
#include <vector>

#include "independentsoft/pst/pst_file.hpp"
#include "independentsoft/pst/folder.hpp"

using namespace independentsoft::pst;

static std::string toUtf8(const text& s)
{
    std::string result;
    for (char16_t c : s)
    {
        if (c < 0x80)
        {
            result += static_cast<char>(c);
        }
        else if (c < 0x800)
        {
            result += static_cast<char>(0xC0 | (c >> 6));
            result += static_cast<char>(0x80 | (c & 0x3F));
        }
        else
        {
            result += static_cast<char>(0xE0 | (c >> 12));
            result += static_cast<char>(0x80 | ((c >> 6) & 0x3F));
            result += static_cast<char>(0x80 | (c & 0x3F));
        }
    }
    return result;
}

int main()
{
    PstFile file("c:\\testfolder\\Outlook.pst");

    Folder* startFolder = file.mailbox_root();

    std::vector<Folder> folders = startFolder->get_folders(true);

    std::map<int64_t, std::string> parents;

    std::string parentFolder = toUtf8(startFolder->display_name());
    parents[startFolder->id()] = parentFolder;

    for (size_t i = 0; i < folders.size(); i++)
    {
        Folder& currentFolder = folders[i];

        parentFolder = parents[currentFolder.parent_id()];

        std::string currentFolderPath = parentFolder + "\\" + toUtf8(currentFolder.display_name());
        parents[currentFolder.id()] = currentFolderPath;

        std::cout << "Id: " << currentFolder.id() << std::endl;
        std::cout << "Name: " << toUtf8(currentFolder.display_name()) << std::endl;
        std::cout << "Type: " << toUtf8(currentFolder.container_class()) << std::endl;
        std::cout << "Item count: " << currentFolder.item_count() << std::endl;
        std::cout << "Path: " << currentFolderPath << std::endl;
        std::cout << "--------------------------------------------------------" << std::endl;
    }

    file.close();
    return 0;
}
