Delete a folder in my home screen Android 4.0, Aquos? My home screen looks like this:

Empty_folder | Application 1 | Application 2 | Application N


When I long press over the folder, I have the option to rename it.  How do I delete the folder, though?  I've been moving them to a different screen, but now I have three screens of blank folders that I accidentally created by trying to rearrange icons.

Also, I wonder how do I switch two icons on my home screen?  When I drag two items into each other, they don't switch but rather create a folder and then add themselves to it, which seems ridiculous.  In any other OS, if I want a new folder, I have to be very specific about that.
If you long press over something in the Aquos, "Peel off" is used to remove it.
