Its main display provides dual directory view panels that may serve as source and destination of a copy or move operation or just two different views of your files. A panel may also be used to view a directory tree, drive statistics or may be turned off altogether, making visible the output of previously executed commands.
A command line is also provided and operates in conjuction with the directory panels to make it much more powerful than a regular CLI including pasting file names from the panel, a command history recall window and command completion from history.
