files uploaded but 404 error - page not found

My story so far,
In my ignorance, I uploaded my files to all of the remote folders, whereas I now understand that I should have only uploaded to the cgi bin file, I notice also that the cgi bin file carries a red error symbol. I notice that although the tutorial shows local files to the left, my local files are all to the right hand side, and the remote files to the left is this just a new layout?
my files have all been placed in the host's public file as instructed.
Can anyone help??
