Open a Remote Directory on an SFTP Server

Demonstrates the Chilkat SFtp.OpenDir method, which opens a remote directory and returns a handle for reading its entries. The only argument is the directory path. Close the handle with CloseHandle when finished.

Background: Listing a directory in SFTP is a handle-based operation, mirroring file access: open the directory to get a handle, read its entries, then close it. The handle is passed to ReadDirListing to retrieve the names and attributes. As with file handles, the directory handle is a server-side resource that should be closed to avoid exhausting the server's limits.
