First of all, bear in mind that SolarWinds TFTP Server is not a common FTP server. TFTP server is actually a different protocol, although based on FTP, which is used mainly for uploads and downloads to hubs, switches, routers and other network devices.
This tool is simple both in design and usage. Its plain, almost austere interface goes straight to the point and wastes no resources in bells and whistles. But this doesn't mean a shortage in functions: the server includes IP security (which means it will only accept connections from a given IP range) and automatic shutdown.
On the downside, we couldn't make use of the many functions provided in the Tools menu, as the program was surprisingly not able to find our default browser.
