Steam Deck Quickie: Transfer Files From PC to Deck with SSH (Under 3 Minutes!) - Reupload
This version has audio :)
SSH allows you to not only remote "shell" to your Steam Deck from another device, but allows you to transfer files to and from your Deck with your PC, phone or any other device with a SFTP capable client.
In less than 3 minutes, you can be set up and ready to move your emulation bios, roms and even full blown Steam games from your PC to your Steam Deck. No sneaker-net files using a flash drive ... no Ext4 format incompatibilities. Just a quick and easy way to integrate your Steam Deck with your file management system.
Note: You don't have to reboot; just use START instead of ENABLE. Just know START is per session and if you reboot, it will shut off SSH.
RECOMMENDED SFTP CLIENTS
Free: WinSCP (https://winscp.net/)
Paid: Directory Opus (https://www.dopus.com)

Note: I realize this is the least secure way of setting up SSH. For those security minded, you may want to check out this thread on Reddit to learn more.
