The SocketTools File Transfer ActiveX control provides a simplified interface for uploading and downloading files over the Internet or an intranet. The control implements the File Transfer Protocol (FTP) and Hypertext Transfer Protocol (HTTP) for transferring files between the local system and a server.

An application can transfer a file with a single method call, simply by specifying a URL, without the need to provide the individual protocol, host, port, file name, and account information. Alternatively, connection and access information may be supplied separately, to allow multiple file transfer operations to be performed in a single server session. In either case, the differences between the supported protocols are kept to a minimum. Additional features such as proxy connections are easily implemented by simply setting a few properties.

The control offers a comprehensive interface that provides everything needed to incorporate file transfer functionality in an application, as well as perform remote file management. In addition to downloading and uploading by file name, URL, and wild card patterns, a developer may use the control for the creation, listing, and removal of directories, as well as renaming and removal of files on the server.

In addition to supporting standard FTP and HTTP connections, the File Transfer Control also supports secure TLS 1.2 and SFTP (SSH 2.0) connections. By simply setting a few properties, a secure connection using up to 256-bit AES encryption can be established, providing your application with the greatest flexibility and highest level of security available.


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.
