A combination of file-attributes (looking at the number of links) and directory-files should do that, I think. > You might try to do it from the number of hard links to the directory, > which will normally be 2 for an empty directory, since users normally > can't create alternate names for a directory.

I'm not an expert on this, but I think it's impossible to create such alternate names, since GNU Find uses this fact to detect directories with no subdirectories. _______________________________________________ Emacs-devel mailing list Emacs-devel@gnu.org http://lists.gnu.org/mailman/listinfo/emacs-devel
