# Check for New Files

Elecraft makes new K3 firmware available by placing files on an Elecraft-provided file server. The K3 Utility program uses the File Transfer Protocol (FTP) to copy new firmware files from Elecraft to the folder you have selected on your computer.

Your computer must be connected to the internet to use this K3 Utility function. See the Manual File Transfer section for a technique to update K3 firmware when your computer is not connected to the internet.
