Detection a removal of a folder from usb-stick

Hello all,

I use QFileSystemModel to detect change with my usb-stick. And I have got a problem. When I delete some folder from usb-stick whereat nothing happens. I don't have got any signals from QFileSystemModel.

When I looked at inside QFileSystemModel, I see what QWindowsFileSystemWatcherEngineThread emit directoryChanged signal with removed = false instead removed = true. Also GetLastError return error number 5 (ERROR_ACCESS_DENIED).

Does anyone know how detect a removal of folder from usb-stick?

Best regards.
