Transfer server of a secure system for unattended remote file and message transfer

A method for automatically transferring a data file from a network drive of a client controlled local area network to a transfer server over the Internet comprises using a first workstation to configure event parameters within event tables of the transfer server. An unattended interface module executed by a processor of a second workstation obtains, from the transfer server, the event parameters stored in the event tables. The event parameters comprise a file name and a directory path. The file name identifies the data file to be uploaded. The directory path identifies an upload directory of the network drive. The second workstation periodically searches the upload directory and, upon locating a data file in the upload directory with the file name, transfers the data file to the transfer server over a secure connection established with the transfer server over the internet.
