Have you looked at org-fstree? http://repo.or.cz/w/org-fstree.git
It generates an org tree for the contents of a directory. It doesn't have an
option to include the size or other file attributes as properties as the moment,
but I don't think this would be hard to add. Andreas and I have been working on
it quite a lot over the last week, I'll see if I can add an option which would
do what you want.
