Notepad++ show open files on the left

In Notepad++, is there a way to show the list of files that are currently open in a list on the left instead of using the default tab-view?

(I'd like it to resemble the way TextPad shows the files that are currently open.)

I'm NOT referring to an Explorer which will allow me to open new files, I just don't like the tabs on top when many files are opened.
