Download an FTP Directory Tree

Demonstrates the Chilkat Ftp2.DownloadTree method, which downloads all selected files and subdirectories beneath the current remote directory and recreates the tree under a local directory. The only argument is the local root. Existing local files are overwritten.

Note: The local paths are relative to the application's current working directory. Absolute paths may also be used. Supply the paths appropriate to your own environment.

Background: This is a full recursive pull — it walks the remote tree and mirrors its structure locally in one call, the backbone of tasks like backing up a server directory or grabbing an entire published site. Unlike the Sync methods it transfers everything selected regardless of what already exists locally; use SetOldestDateStr or the file/directory filter properties to narrow what is included.
