Is it possible to delete a not empty directory in dired-mode?

I get the following error in Dired log:

(file-error Removing directory directory not empty <name of directory I try
to delete>)

1 of 1 deletion failed
Fri Apr 12 09:56:37 2002 Buffer `<name of directory I am
inspecting in dired mode>'
I do not know if this is a NTEmancs problem, so please excuse if this is a
wrong posted request:

Thanks for any hint,
