Hi,

as far as I know the answer is NO.
I think you have to write your own code using QDir::entryInfoList(), QDir::makePath() and QFile::copy()

For any lost Googlers - looking for some quick copy-paste.

I've had success with this function :)

    bool copyRecursively(QString sourceFolder, QString destFolder)
    {
        bool success = false;
        QDir sourceDir(sourceFolder);

        if(!sourceDir.exists())
            return false;

        QDir destDir(destFolder);
        if(!destDir.exists())
            destDir.mkdir(destFolder);

        QStringList files = sourceDir.entryList(QDir::Files);
        for(int i = 0; i< files.count(); i++) {
            QString srcName = sourceFolder + QDir::separator() + files[i];
            QString destName = destFolder + QDir::separator() + files[i];
            success = QFile::copy(srcName, destName);
            if(!success)
                return false;
        }

        files.clear();
        files = sourceDir.entryList(QDir::AllDirs | QDir::NoDotAndDotDot);
        for(int i = 0; i< files.count(); i++)
        {
            QString srcName = sourceFolder + QDir::separator() + files[i];
            QString destName = destFolder + QDir::separator() + files[i];
            success = copyRecursively(srcName, destName);
            if(!success)
                return false;
        }

        return true;
    }

Qt do not support recursively copy of a directory. Instead, you may take a look with my library , QtShell, it could manipulate files by a shell command style API. It supports a recursively copy of files and handled several more conditions:

https://github.com/benlau/qtshell#cp

Example

cp("-a", ":/*", "/target"); // copy all files from qrc resource to target path recursively

cp("tmp.txt", "/tmp");

cp("*.txt", "/tmp");

cp("/tmp/123.txt", "456.txt");

cp("-va","src/*", "/tmp");
