This screen gives a snapshot of the calculator's memory and of the directory tree. The screen shows that the calculator has three memory ports (or memory partitions), port 0:IRAM, port 1:ERAM, and port 2:FLASH . Memory ports are used to store third party application or libraries, as well as for backups. The size of the three different ports is also indicated. The fourth and subsequent lines in this screen show the calculator's directory tree. The top directory (currently highlighted) is the Home directory, and it has predefined into it a sub-directory called CASDIR. The File Manager screen has three functions associated with the soft-menu keys: @CHDIR (A): Change to selected directory @CANCL (E): Cancel action @@OK@@ (F): Approve a selection For example, to change directory to the CASDIR, press the down-arrow key, ˜, and press @CHDIR (A). This action closes the File Manager window and returns us to normal calculator display. You will notice that the second line from the top in the display now starts with the characters { HOME CASDIR } indicating that the current directory is CASDIR within the HOME directory.
