FTP Server: List all files name

FTP Server: List all files name 

This tutorial represents how to list all the files name on FTP server using java.

List all Files name:

We can list all the files name with the help of FTPClient class. FTPClient class provides different methods to operate the FTP server operations. There is no direct method to list only files of the ftp server. So first call method client.listFiles() to list all the files and directory and then check, it is file or not by using isFile() FTPFile method. Now you can display name of file by calling method file.getName().

Example : This example represents how to get list of files name.

import java.io.IOException;

import org.apache.commons.net.ftp.FTPClient;
import org.apache.commons.net.ftp.FTPConnectionClosedException;
import org.apache.commons.net.ftp.FTPFile;

class FTPListFiles {
	public static void main(String[] args) throws IOException {
		FTPClient client = new FTPClient();
		boolean result;
		try {
			client.connect("localhost");
			result = client.login("admin", "admin");

			if (result == true) {
				System.out.println("User successfully logged in.");
			} else {
				System.out.println("Login failed!");
				return;
			}
			FTPFile[] files = client.listFiles();
			System.out
					.println("Files on Ftp Server : ");
			for (FTPFile file : files) {
				if (file.isFile()) {
					System.out.println("File name : " + file.getName());
				}
			}

		} catch (FTPConnectionClosedException e) {
			System.out.println(e);
		} finally {
			try {
				client.disconnect();
			} catch (FTPConnectionClosedException e) {
				System.out.println(e);
			}
		}
	}
}

Output :

User successfully logged in.
