# Folder Location

Firmware files are copied from an Elecraft file server to a firmware folder (a file directory) on your computer before they are sent to the K3. This section helps you choose the folder on your computer to store firmware files.

The K3 Utility creates a folder for this purpose.

On Mac OS X - the default folder location is:
Volume:Users:User:Library:Application Support:Elecraft:K3 Firmware:

On Linux - the default folder location is:
/USER$/Elecraft/K3_Firmware/

You may use this folder or choose another by using the Browse button to start a Browse for Folder dialog.
