Yeah, what Lisa said. Also, I would recommend that you perhaps open the file you want to work on, save the original file with a new name so you have a backup copy of that original. Then open again the original file name (which is the one you need to upload to your site) and work on that. If you mess up, open up the file that you re-named, as that's the original, you can name it back to the original file name again so you didn't lose anything or mess anything up. ALWAYS have a backup.
