Is there a functioning FTP homebrew out for the Switch so that we can use a client such as SCP or FileZilla to copy files to and from the switch?
Yes. TomGer's SD Files comes with it.
Comes with what? I use SX OS
Where do I find my switch ip address?:
Don't need an ftp client if using windows
Just open a windows explorer windows and type this in the address bar
ftp://ipaddress:5000
Where ipaddress is your switch IP address
