For modern applications, developers often use FluentFTP , a high-level library that simplifies batch operations. It includes optimized methods like DownloadFiles() and DownloadDirectory() that handle recursion and parallel transfers automatically.

: Mirror a complete remote folder structure locally in a single call.

using System; using System.IO; using System.Net; using System.Collections.Generic; public void DownloadAllFiles(string ftpUrl, string username, string password, string localPath) { // 1. Get the list of files FtpWebRequest listRequest = (FtpWebRequest)WebRequest.Create(ftpUrl); listRequest.Method = WebRequestMethods.Ftp.ListDirectory; listRequest.Credentials = new NetworkCredential(username, password); List files = new List (); using (FtpWebResponse listResponse = (FtpWebResponse)listRequest.GetResponse()) using (StreamReader reader = new StreamReader(listResponse.GetResponseStream())) { string line; while ((line = reader.ReadLine()) != null) { files.Add(line); } } // 2. Download each file foreach (string file in files) { string remoteFileUrl = $"{ftpUrl}/{file}"; string localFilePath = Path.Combine(localPath, file); FtpWebRequest downloadRequest = (FtpWebRequest)WebRequest.Create(remoteFileUrl); downloadRequest.Method = WebRequestMethods.Ftp.DownloadFile; downloadRequest.Credentials = new NetworkCredential(username, password); using (FtpWebResponse downloadResponse = (FtpWebResponse)downloadRequest.GetResponse()) using (Stream responseStream = downloadResponse.GetResponseStream()) using (FileStream fileStream = new FileStream(localFilePath, FileMode.Create)) { responseStream.CopyTo(fileStream); } } } Use code with caution. Simplified Method (FluentFTP)

: Loop through the retrieved list and initiate a DownloadFile request for each entry. Example Implementation:

: Downloads a specific list of remote files to a local directory.

Downloading multiple files from an FTP server in can be achieved using native .NET libraries or specialized third-party packages . Because the standard FTP protocol does not support a "download all" command, you must typically list the directory contents first and then iterate through the files to download them individually. Native .NET Method (FtpWebRequest)

: Supports Task-based Asynchronous Pattern (TAP) and can download files concurrently to improve speed. Key Considerations C# Download all files and subdirectories through FTP

: Use the ListDirectory or ListDirectoryDetails method to get a list of filenames from the server.
