Total Commander is a mobile version for Android that offers the same benefits as the Windows version.

With the Total Commander, you can move, copy, and paste directories and subdirectories in their entireties. You can also create new folders, rename folders, and delete folders but you must be careful because you won't have a trash bin to put it all in.

You are also able to put a widget on your desktop that will have an access link to your FTP client. It could also have an internal editor that will work with all applications. The app might be ugly but it is practical.
