FTP, FTPS Component for .NET 2.1

FTP, FTPS Component for .NET 2.1 helps to transfer files directly from your application using FTP/SSL (an extension of FTP which is fast becoming a standard for secure FTP) more easily. FtpClient class provides a number of convenience asynchronous methods and events that allow you to quickly create applications which can handle file transfers simultaneously.

The library also offers the flexibility, ease of use and rapid development features of a component without the complexities of working with the native socket class or in-depth knowledge of how the File Transfer Protocols are implemented.
