[Interest] When is QDir::Drives useful?

Since  Im no longer sure what this discussion is about... Back to the original question, when is QDir::drives() useful..

Here is code... 
#include <QCoreApplication>
#include <QDir>
#include <QFileInfo>
#include <QDebug>
int main( int argc, char ** argv )
    QFileInfoList drives = QDir::drives();
    foreach( const QFileInfo & curr, drives )
        qDebug() << curr.absoluteFilePath();

Which when run as a console app returns:

This is on a Win7 machine, running Qt 4.7.4.. However this is the results I have been getting/expecting for years...

So what is the issue?  Are we completely off QDir::Drives?

Just tested.  QDir::rootPath() returns "C:\".

"My Computer" is not an existing directory though.  It's a programmatically constructed, uhm, construct.

An alternative way to ask the question is: If you open a command prompt (cmd.exe), where would you have to "cd" into so that "dir" would list drives?
