Create a private directory under user

[thru]

Did you try like this?

if(file.setPermissions(QFile::ReadOwner|QFile::WriteOwner)){
  qDebug() << "Permissions changed";
} else {
  qDebug() << "Couldn't change permissions";
}

if(file.setPermissions(QFile::ReadOwner|QFile::WriteOwner)){
  qDebug() << "Permissions changed";
} else {
  qDebug() << "Couldn't change permissions";
}

To copy to clipboard, switch view to plain text mode 

Yes, I tried but I did witht the file open and didn't work (setPermissions was returning true but the actual permissions didn't change).
I've just tried not opening the file and it woks perfectly.
Thanks!
