The FTPGetList method can be used to list the contents of the current local or remote folder. The "local" or "remote" keyword is used to select a local or remote listing. The number of recursive levels of subfolders to list can also be specified. The list of retrieved files and folders is provided as a FTPListItems collection that can be enumerated.
