Use a proxy model for sorting.

QSortFilterProxyModel

Basically using this, i tried to play around and did something like this:

QSortFilterProxyModel *proxyModel = new QSortFilterProxyModel(this);
 proxyModel->setSourceModel(pSystemPrimaryModel);
 
 // Set the QStandardItemModel model of QTreeView to display audio and video files with details
 ui->PrimTreeView->setModel(proxyModel);

QSortFilterProxyModel *proxyModel = new QSortFilterProxyModel(this);
 proxyModel->setSourceModel(pSystemPrimaryModel);

 // Set the QStandardItemModel model of QTreeView to display audio and video files with details
 ui->PrimTreeView->setModel(proxyModel);

To copy to clipboard, switch view to plain text mode 

it didnt work..... Looks like I have to use some functions

Since you want to change the order of the drives only, obviously just using a proxy that sorts *everything* will not work. You need to subclass it and reimplement the comparision method taking into consideration *what* you are sorting. And I have no idea why you used QStandardItemModel instead of QFileSystemModel in the last snippet. Maybe that's why it "didn't work" (whatever that means)

Well That was a typo from my side. I have used QFileSystemModel only. Looks like I have to re-implement the comparison method.
