Remove a Remote Directory on an SFTP Server

Demonstrates the Chilkat SFtp.RemoveDir method, which deletes a remote directory. The only argument is the directory path.

Background: Most SFTP servers refuse to remove a directory that is not empty, so deleting a populated tree means removing its files and subdirectories first — the inverse of building a path level by level. There is no single "recursive delete" in the SFTP protocol; a client implements it by listing, descending, and removing bottom-up.
