The File Transfer Protocol (FTP) control provides a comprehensive API which supports both high level operations, such as uploading or downloading files, as well as a collection of lower-level file I/O functions. In addition to file transfers, an application can create, rename and delete files and directories, search for files using wildcards and perform other common file management functions.

Files can be stored on the local file system or in memory, depending on the needs of your application and multiple file transfers be performed using a single function call. The control can also be used to manage files on the server and supports many of the common protocol extensions that can be used to access the remote file system. It understands a number of different directory listing formats, including those typically used with UNIX and Linux based systems, Windows server platforms, NetWare servers and VMS systems.

This control supports active and passive mode file transfers, firewall compatibility options, proxy servers and secure file transfers using the standard SSL/TLS and SFTP protocols. Secure file transfers support implicit and explicit SSL sessions, client certificates and up to 256-bit AES encryption.


The SocketTools ActiveX Edition components are self-registering controls compatible with any programming language that supports COM (Component Object Model) and the ActiveX control specification. If you are using Visual Basic 6.0 you must have Service Pack 6 (SP6) installed. It is recommended that you install all updates for your development tools.

This control is supported on Windows 7, Windows Server 2008 R2 and later versions of the desktop and server platforms. If you are using Windows 7, you must have Service Pack 1 (SP1) installed as a minimum requirement. It is recommended that you install the current service pack and all critical updates available for the operating system.

This product includes both 32-bit and 64-bit ActiveX controls. Native 64-bit CPU support requires the latest 64-bit version of Windows 7, Windows Server 2008 R2 or later versions of the Windows operating system.


When you distribute an application that uses this control, you can either install the file in the same folder as your application executable or as a shared component in the appropriate system folder. If you install the control in the system folder, it is important that you distribute the correct version for the target platform and it must be registered. If you install the control in the same folder as your executable, it is recommended that you use registration-free activation or COM redirection to ensure that the correct version of the control is loaded by the application.
