## What it is
FluentFTP is a fully managed FTP and FTPS client library for .NET and .NET Standard, written entirely in C# with no external dependencies and optimized for speed. It supports a wide range of FTP server types, secure TLS connections, async/await, FXP server-to-server transfers, proxies, and extensive file management commands.

## Use cases
- upload and download files over ftp or ftps from a .net application
- connect to ftp servers with ssl/tls and client certificates
- transfer files between two ftp servers with fxp
- parse directory listings from unix, iis, proftpd, and other ftp servers
- use an ftp client from powershell scripts
- compute file hashes and checksums over ftp
- manage file permissions and chmod on an ftp server

## When to choose
- you need a fast, dependency-free FTP/FTPS client in .NET or .NET Standard
- your app must support many FTP server types including mainframe listings
- you want async/await FTP operations or PowerShell automation
- you need FXP server-to-server transfers or FTP proxy support

## When to avoid
- you need SFTP over SSH, which is a different protocol
- you are not working in the .NET ecosystem
- you need a GUI FTP client rather than a programmable library
