TextEdit wants to open index.html as a web page, because it's being a little too smart for its own good. So... we'll tell it we want to edit the file, instead of see what it looks like. 1) Launchpad is the round silver rocket ship over toward the left end of the dock. Click it. 2) Hunt for "TextEdit". The icon is a page with a pen over it. Click on it. 3) When TextEdit opens, go to the menu bar and go through: TextEdit -> Preferences -> Open and Save 4) Check the option that says "Display HTML files as HTML code instead of formatted text". 5) Red button upper left to close the window. --- Now, when you say "edit" in FileZilla, it should open in TextEdit as normal text.
