PuTTY is indeed a robust application, but ExtraPuTTY takes it up a notch: with it, you can send and receive any type of data using applications through protocols like Raw, Rlogin, Telnet, and SSH.
For those unfamiliar with PuTTY, it's one of the go-to tools for IT technicians to connect to a router, firewall, or server via SSH, serial, or Telnet.
Once you download the app from its official page, you'll see its simple interface, but it's packed with powerful features. Unlike PuTTY, it lets you execute root commands, making it easier to create and manage sessions. You can also analyze the information flow from a website to servers or user devices (HTML report), and upload firmware files to a router via serial cable.
It also includes an FTP client (FTPLoader), which is one of the best advantages of this extra version of PuTTY.
If you really need to transfer files across different protocols, ExtraPuTTY is one of the best options you'll find. ExtraPuTTY is a free application available for Windows operating systems.
