I'm implement a QFileDialog::getExistingDirectory() over a click of a button ......

but the ExistingDirectory is showing me all the directories including the CD-ROM and the
Maped-Drives .......

I have Two Maped_Drives ,CD-ROM and CD-Writer on my system .....

Is there any way i can filter some of the existing Drives on my System
