Checking if a folder exists (and creating folders) in Qt, C++

Question

In Qt, how do I check if a given folder exists in the current directory?
If it doesn\'t exist, how do I then create an empty folder?

Answer 1

If you need an empty folder you can loop until you get an empty folder

    QString folder= QString ("%1").arg(QDateTime::currentMSecsSinceEpoch());
    while(QDir(folder).exists())
    {
         folder= QString ("%1").arg(QDateTime::currentMSecsSinceEpoch());
    }
    QDir().mkdir(folder);

This case you will get a folder name with a number .
