The Tree View button enables the user to invoke the PADE Tree View window. The Tree View window is one of the most unique features of PADE. This window enables the user to add hosts to the Host list, add files to the files list for a particular host, move files between hosts, modify hosts, and delete hosts in a completely graphical environment. The Tree View button is disabled unless there is at least one entry in the Host list. The PADE Tree View window is discussed in detail later in this chapter.
