From Weird Solutions:
A great little TFTP server for temporary use (user-level application) for Windows 7 and previous desktop operational systems. A TFTP GUI client is also included. The interface shows you file-transfers in real-time The limited version is free for non-commercial use.
Having used numerous TFTP packages to communicate with Cisco products, this is by far the best and easiest software I have used to date. Running smoothly on both XP Professional and Windows 2000, I will be fully recommending this product to my customers and students! John Pepper, Managing Director, www.minxtechnology.co.uk"
