 [](https://www.nuget.org/packages/FluentFTP) [](https://www.nuget.org/packages/FluentFTP) [](https://github.com/robinrodricks/FluentFTP/graphs/contributors) [](https://app.codacy.com/project/robinrodricks/FluentFTP/dashboard) [](https://github.com/robinrodricks/FluentFTP/blob/master/LICENSE.TXT) FluentFTP is a fully managed FTP and FTPS library for .NET & .NET Standard, optimized for speed. It provides extensive FTP commands, File uploads/downloads, SSL/TLS connections, Automatic directory listing parsing, File hashing/checksums, File permissions/CHMOD, FTP proxies, FXP transfers, UTF-8 support, Async/await support, Powershell support and more. It is written entirely in C#, with no external dependencies. FluentFTP is released under the permissive MIT License, so it can be used in both proprietary and free/open source applications.  ## Features - Full support for [FTP](https://github.com/robinrodricks/FluentFTP/wiki/FTP-Support), [FXP](https://github.com/robinrodricks/FluentFTP/wiki/FXP-Server-To-Server#how-does-fxp-transfer-work), [FTPS](https://github.com/robinrodricks/FluentFTP/wiki/FTPS-Connection#faq_ftps) (FTP over SSL), [FTPS with client certificates](https://github.com/robinrodricks/FluentFTP/wiki/FTPS-Connection#faq_certs) and [FTPS with CCC](https://github.com/robinrodricks/FluentFTP/wiki/FTPS-Connection#faq_ccc) (for FTP firewalls) - **File management:** - File and directory listing for [all major server types](https://github.com/robinrodricks/FluentFTP/wiki/Directory-Listing#faq_listings) (Unix, Windows/IIS, Azure, Pure-FTPd, ProFTPD, Vax, VMS, OpenVMS, Tandem, HP NonStop Guardian, IBM OS/400, AS400, Windows CE, Serv-U, etc) - Fully recursive directory listing and directory deletion (manual recursion and server-side recursion) - Easily upload and download a file from the server with [progress tracking](https://github.com/robinrodricks/FluentFTP/wiki/File-Transfer#how-can-i-track-the-progress-of-file-transfers) - Easily upload and download a directory from the server with [easy synchronization modes](https://github.com/robinrodricks/FluentFTP/wiki/Directory-Transfer#what-is-the-difference-between-the-mirror-and-update-modes) - Easily transfer a file or folder directly from [one server to another](https://github.com/robinrodricks/FluentFTP/wiki/FXP-Server-To-Server#how-does-fxp-transfer-work) using the FXP protocol - Conditionally transfer files using [rule based whitelisting and blacklisting](https://github.com/robinrodricks/FluentFTP/wiki/Rules#what-kinds-of-rules-are-supported-and-how-do-rules-work) - Automatically [verify the hash](https://github.com/robinrodricks/FluentFTP/wiki/File-Hashing#faq_verifyhash) of a file & retry transfer if hash mismatches - Configurable error handling (ignore/abort/throw) for multi-file transfers - Easily read and write file data from the server using standard streams - Create, append, read, write, rename, move and delete files and folders - Recursively deletes folders and all its contents - Get file/folder info (exists, size, security flags, modified date/time) - Get and set [file permissions](https://github.com/robinrodricks/FluentFTP/wiki/File-Permissions) (owner, group, other) - Absolute or relative paths (relative to the ["working directory"](https://github.com/robinrodricks/FluentFTP/wiki/File-Management)) - Compare a local file against a remote file using the [hash/checksum](https://github.com/robinrodricks/FluentFTP/wiki/File-Hashing#faq_comparefile) (MD5, CRC32, SHA-1, SHA-256, SHA-512) - Dereference of symbolic links to calculate the linked file/folder - [Throttling](https://github.com/robinrodricks/FluentFTP/wiki/File-Transfer#faq_throttle) of uploads and downloads with configurable speed limit - **FTP protocol:** - Automatic detection of [working connection settings](https://github.com/robinrodricks/FluentFTP/wiki/Automatic-Connection#faq_autodetect) and automatic [connection negotiation](https://github.com/robinrodricks/FluentFTP/wiki/Automatic-Connection#faq_autoconnect) - Automatic detection of the [FTP server software](https://github.com/robinrodricks/FluentFTP/wiki/Server-Information#faq_servertype) and its [capabilities](https://github.com/robinrodricks/FluentFTP/wiki/Directory-Listing#faq_recursivelist) - Extensive support for [FTP commands](https://github.com/robinrodricks/FluentFTP/wiki/FTP-Support), including some server-specific commands - Easily send [server-specific](https://github.com/robinrodricks/FluentFTP/issues/88) FTP commands using the `Execute()` method - Explicit and Implicit [SSL connections](https://github.com/robinrodricks/FluentFTP/wiki/FTPS-Connection#faq_ftps) are supported for the control and data connections using .NET's `SslStream` - Passive and active data connections (PASV, EPSV, PORT and EPRT) - Supports Unix CHMOD, PRET, ProFTPD's SITE MKDIR and RMDIR commands, Serv-U's RMDA command - Supports [FTP Proxies](https://github.com/robinrodricks/FluentFTP/wiki/FTPS-Proxies#faq_loginproxy) (User@Host, HTTP 1.1, BlueCoat) - [FTP command logging](https://github.com/robinrodricks/FluentFTP/wiki/Logging#faq_log) using `TraceListeners` (passwords omitted) to [trace](https://github.com/robinrodricks/FluentFTP/wiki/Logging#faq_trace) or [log output](https://github.com/robinrodricks/FluentFTP/wiki/Logging#faq_logfile) to a file - SFTP is not supported as it is FTP over SSH, a completely different protocol (use [SSH.NET](https://github.com/sshnet/SSH.NET) for that) - **Asynchronous support:** - Synchronous and asynchronous methods using `async`/`await` for all operations - Asynchronous methods for .NET 4.0 and below using `IAsyncResult` pattern (Begin*/End*) - All asynchronous methods can be cancelled midway by passing a `CancellationToken` - All asynchronous methods honor the `ReadTimeout` and automatically cancel themselves if timed out - Improves thread safety by cloning the FTP control connection for file transfers (optional) - Implements its own internal locking in an effort to keep transactions synchronized - **Extensible:** - Easily add support for custom non-standard FTP servers (see the [Custom Servers](https://github.com/robinrodricks/FluentFTP/wiki/Custom-Servers) page) - Easily add support for more file or directory filtering rules (simply extend [`FtpRule`](https://github.com/robinrodricks/FluentFTP/wiki/Class-FtpRule)) - Easily add support for more proxy types (simply extend [`FtpClientProxy`](https://github.com/robinrodricks/FluentFTP/blob/master/FluentFTP/Proxy/FtpClientProxy.cs)) - Easily add unsupported directory listing parsers (see the [`CustomParser`](https://github.com/robinrodricks/FluentFTP/blob/master/FluentFTP.CSharpExamples/CustomParser.cs) example) - Easily add custom logging/tracing functionality using [`FtpTrace.AddListener`](https://github.com/robinrodricks/FluentFTP/wiki/Logging#faq_log) - Easily add your own Powershell commands by extending the scripts in [`FluentFTP.ps1`](https://github.com/robinrodricks/FluentFTP/wiki/Powershell) ## Releases Stable binaries are released on NuGet, and contain everything you need to use FTP/FTPS in your .Net/CLR application.
