I cannot delete that folder. If I open a file in a folder In both cases, I have found that Q-Dir still is holding open the file (via a file handle). Even if I exit out of Q-Dir (File -> Exit), the file is still held by Q-Dir. This led me to find that Q-Dir is still listed in the Task Manager as a running process. I then have to END TASK on Q-Dir manually to terminate it in order to release the file handles.
