Create new PST and import items from an existing PST

The following example shows you how to create a new PST file, read folders and items from an existing PST file and import them into the new file.

C++ example

#include <iostream>
#include <memory>
#include <optional>
#include <vector>

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

using namespace independentsoft::pst;

int main()
{
    PstFile sourceFile("c:\\testfolder\\Source.pst");
    std::shared_ptr<PstFile> targetFile = PstFile::create("c:\\testfolder\\New.pst");

    Folder* sourceStartFolder = sourceFile.mailbox_root();
    Folder* targetStartFolder = targetFile->mailbox_root();

    std::vector<Folder> folders = sourceStartFolder->get_folders(false);

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

        Folder newFolder(sourceFolder.display_name());
        targetStartFolder->add_folder(newFolder);

        std::optional<Folder> targetFolder = targetStartFolder->get_folder(sourceFolder.display_name());

        std::vector<std::shared_ptr<Item>> items = sourceFolder.get_items();

        if (!items.empty() && targetFolder)
        {
            std::vector<Item> newItems;

            for (size_t j = 0; j < items.size(); j++)
            {
                newItems.push_back(*items[j]);
            }

            targetFolder->add_items(newItems);
        }
    }

    targetFile->save();

    std::cout << "Done." << std::endl;
    return 0;
}
