Check if an FTP Listing Entry is a Symbolic Link

Demonstrates the Chilkat Ftp2.GetIsSymbolicLink method, which returns whether a cached directory-listing entry is a symbolic link. The only argument is a zero-based index. This information is available only when the server's listing format reports it.

Background: Symbolic links matter because following one can lead outside the expected directory or into a cycle, so recursive operations often need to identify and skip them. Unlike the file/directory distinction, symlink information is not always present — only listing formats that mark links (typically Unix-style LIST output) expose it, and this returns false when the server does not.
