How to create a directory on an FTP server using C#?

Ok, so I already can upload a file to an FTP server: How to upload a file to an FTP server using C#?

However, now I need to create a directory first.

It follows some basic steps:

  1. Open a request using the full destination ftp path: Ftp://Ftp.Server.tld/ or Ftp://Ftp.Server.tld/Some/Path
  2. Configure the connection request
  3. Call GetResponse() method to actually attempt to create the directory
  4. Verify that it worked.

See the steps inside the source as comments:

using System;
using System.IO;
using System.Net;

namespace CreateDirectoryOnFtpServer
    class Program
        static void Main(string[] args)
            CreateDirectoryOnFTP("ftp://ftp.server.tld", /*user*/"User1", /*pw*/"Passwd!", "NewDirectory");


        static void CreateDirectoryOnFTP(String inFTPServerAndPath, String inUsername, String inPassword, String inNewDirectory)
            // Step 1 - Open a request using the full URI, ftp://ftp.server.tld/path/file.ext
            FtpWebRequest request = (FtpWebRequest)FtpWebRequest.Create(inFTPServerAndPath + "/" + inNewDirectory);

            // Step 2 - Configure the connection request
            request.Credentials = new NetworkCredential(inUsername, inPassword);
            request.UsePassive = true;
            request.UseBinary = true;
            request.KeepAlive = false;

            request.Method = WebRequestMethods.Ftp.MakeDirectory;

            // Step 3 - Call GetResponse() method to actually attempt to create the directory
            FtpWebResponse makeDirectoryResponse = (FtpWebResponse)request.GetResponse();

All right, now you have created a directory on the FTP server.

    I keep getting a Remote server returned an error: (550) File unavailable (not found, no access) using:

    FtpWebRequest req = (FtpWebRequest)WebRequest.Create(custPath);
    req.Credentials = new NetworkCredential("username", "password");
    req.UsePassive = true;
    req.UseBinary = true;
    req.KeepAlive = false;
    req.Method = WebRequestMethods.Ftp.MakeDirectory;
    FtpWebResponse makeDirectoryResponse = (FtpWebResponse)req.GetResponse();

    I need to make a series of folders on the ftp server and then send up files. Making the folders just isn't working for me.

    I was having trouble using this code, it works for the first time but if you are trying to upload
    multiple files and you need to check the existence of directory more than once it was not working. However, with a slight change this code works for both cases, where directory is the full ftp path

    private static bool FtpDirectoryExists(string directory, string username, string password)

    var request = (FtpWebRequest)WebRequest.Create(directory);
    request.Credentials = new NetworkCredential(username, password);
    request.Method = WebRequestMethods.Ftp.ListDirectory;

    FtpWebResponse response = (FtpWebResponse)request.GetResponse();
    catch (WebException ex)
    FtpWebResponse response = (FtpWebResponse)ex.Response;
    if (response.StatusCode == FtpStatusCode.ActionNotTakenFileUnavailable)
    return false;
    return true;
    return true;
