Deletion does not resume after server disconnects

[Marc]

I have a folder on my ftp server that contains thousands of files and some subfolders. I want to delete this folder and accidentally the server disconnects. Filezilla automatically re-connects, but does not resume the deletion because it finds not empty directories that can not be deleted. It seems it skipped the file deletion and so it is not able to finish the deletion.
