This doesn't necessarily work on directories, though, even though it's
in the Directories package.  The description of the Size function is:

# Returns the size of the external file represented by Name. The size
of an
# external file is the number of stream elements contained in the
file. If the
# external file is not an ordinary file, the result is implementation-
defined.

and a directory is certainly not an ordinary file.  So if you give it
a directory name as the Name, it could raise an exception (possibly
Name_Error, but not necessarily), or it could return a result that
means something implementation-defined, or it could return meaningless
garbage.
