Fastest way to delete a tree of empty directories in batch file

Question

I need to write a batch file that received a directory that contains a huge number of empty sub-directories and deletes them all.

What's the fastest way of doing this? (by fast I mean not like what Windows Explorer does when you try to delete such a directory...)

Clarification:

I'm not trying to delete only empty directories. It just so happens that this dir I'm trying to delete is mostly empty sub-dirs.

Answer 1

rd yourdirname /s/q

Will do the job regardless of whether they are empty or not.

Answer 2

I'm not sure if I understood the question. If you just want to delete the tree then you can just use rd /s. However, if you only want to delete empty directories, then you can do the following using Cygwin.

find -type d -empty | xargs rmdir

The standard IT build where I work has Cygwin installed, and I've used this more than once.
