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.
- Full support for FTP, FXP, FTPS (FTP over SSL), FTPS with client certificates and FTPS with CCC (for FTP firewalls)
- File management:
- File and directory listing for all major server types (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
- Easily upload and download a directory from the server with easy synchronization modes
- Easily transfer a file or folder directly from one server to another using the FXP protocol
- Conditionally transfer files using rule based whitelisting and blacklisting
- Automatically verify the hash of a file & retry transfer if hash mismatches

- 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 (owner, group, other)
- Absolute or relative paths (relative to the "working directory")
- Compare a local file against a remote file using the hash/checksum (MD5, CRC32, SHA-1, SHA-256, SHA-512)
- Dereference of symbolic links to calculate the linked file/folder
- Throttling of uploads and downloads with configurable speed limit
- FTP protocol:
- Automatic detection of working connection settings and automatic connection negotiation
- Automatic detection of the FTP server software and its capabilities
