Can you post a screen capture of what you mean? I only see two areas when I look at a folder.
The left side is the Navigation pane which you can get rid of by clicking Organize, Layout, and uncheck Navigation Pane.

I don't know what you mean by "that one at bottom" as I don't have one at the bottom.

Again, for icons, please post a screen capture. Where do you see the text icon? Examples please.

thanks man, got rid of both.
bottom one was detail pane.
