Copy directory using Qt

Question

I want to copy a directory from one drive to another drive. My selected directory contains many sub directories and files.

How can I implement the same using Qt?

Answer 1

void copyPath(QString src, QString dst)
{
    QDir dir(src);
    if (! dir.exists())
        return;

    foreach (QString d, dir.entryList(QDir::Dirs | QDir::NoDotAndDotDot)) {
        QString dst_path = dst + QDir::separator() + d;
        dir.mkpath(dst_path);
        copyPath(src+ QDir::separator() + d, dst_path);
    }

    foreach (QString f, dir.entryList(QDir::Files)) {
        QFile::copy(src + QDir::separator() + f, dst + QDir::separator() + f);
    }
}
