Downloading and Uploading is just as easy as dragging from left to right or right
to left. First let's download something from the public_html folder to the desktop.
We'll take this audio.html file and simply drag it over. Now let's upload it.
We'll delete the one on our server space and put it back. Now we can get rid
of the one on our desktop and we're back to where we started. Note that to download
a folder you will be warned that SSH's sftp client can't yet download directories
but it's going to use Secure Copy Protocol instead. That's fine. This is the
secure copy file. You'll have to authenticate again, and we're done.
