FIGURE 05 introduces the "select files" dialog. The
primary control selection 0210 in the mind of the user is likely to be creation of the
selection list 0520 of original data files 0220. The ability to select multiple files
at a time for input is a common feature of graphical user interfaces.
The "select files" dialog offers five selection
buttons 0510.
Button 0511, "select files from another drive",
is an artifice that substantially speeds up display of directory locations 0530 and
original data file names 0540. The Windows version of the computer program 0930
starts with one hard disk drive only in the directory locations area 0530. This
saves time the program would otherwise use having to cycle through all available
drives; such cycling carries a penalty of several seconds for each removable
media drive that is currently empty. The "select files from another drive"
button 0511 provides flexibility, should the user wish to access other
drives.
Button 0512 "add selected folders and subfolders
to list" and button 0513 "remove selected folders and subfolders from list" both
require that a folder be highlighted by the user in the directory location area
0530, found in the lower left panel in the screen image in FIGURE 05. Button 0512
adds all files in the highlighted folder and its subfolders to the current
selection list of data files 0520. Button 0513 removes them from the list.
Button 0514 "add selected files to list" and
button 0515 "remove selected files from list" both require that one or more files
be highlighted by the user in the original data file name area 0540, found in the
lower right panel in the screen image in FIGURE 05. Button 0514 adds the files
to the current selection list of data files 0520. Button 0515 removes them from
the list.
