Directory Existence Check

How to test if a directory exists on an FTP server.

A good way to check to see if a directory already exists is to try to "cd" to that remote directory by calling ChangeRemoteDir. If it succeeds, then the directory exists. If not, then it does not exist. An alternative method is to set the ListPattern = "*" and then iterate over the files/directories, looking for the directory.
