Get a Remote FTP File's Size by Name

Demonstrates the Chilkat Ftp2.GetSizeByName method, which returns the size in bytes of a named file in the current remote directory as a 32-bit integer. The only argument is the filename — a name, not a path. It returns -1 when the file is not found or the size cannot be obtained.

// Important: Don't forget to include the call to System.loadLibrary
// as shown at the bottom of this code sample.
