New Post: Going into subdirectories when extracting?

I can't find a way to go into subdirectories while extracting an archive.

An archive entry has an IsDirectory flag, but there doesn't seem to be anything to do with a directory entry. I would expect it to have a collection of entries to iterate.

All of the examples and the test cases just skip directories.

Am I missing something obvious, or is there no support for nested directories?

Thanks!
