Almost all of the desktop systems i've used since the mid '90s have a Windows-based tcp/ip product installed. One of the selections is FTP. I've used more than a dozen different products, but they all have a similar "look and feel" for FTP.
When launched, an address to connet to is shown near the top (like the url in a brower window) and the remainder of the screen is split between the Local system and the Remote system. The user positions themself at the appropriate location on both systems, selects the "files to transfer, selects the transfer mode, and clicks to send/receive.
The specifics can vary between products, so it would be best to ask your desktop or network support people what is available to you.
Hope this helps,
