public class FtpListDemo {
public static void main(String[] args) {
FTPClient client = new FTPClient();

// no file found an empty array will be returned.
//
String[] names = client.listNames();
for (String name : names) {
System.out.println("Name = " + name);
}
FTPFile[] ftpFiles = client.listFiles();
for (FTPFile ftpFile : ftpFiles) {
//
// Check if FTPFile is a regular file
//
if (ftpFile.getType() == FTPFile.FILE_TYPE) {
System.out.println("FTPFile: " + ftpFile.getName() + "; " +
FileUtils.byteCountToDisplaySize(ftpFile.getSize()));
}
}
client.logout();
} catch (IOException e) {
e.printStackTrace();
} finally {
