The main window shows the name and icon of each volume as well as their size, used space, free space, percent used, percent free and a "thermometer" graphic representation. It is possible to sort the display by any of these items. If a volume is locked, a padlock icon is shown to the left of the drive name. Nearly-full volumes are hilighted in a used selectable color at a user-specified threshold. The bottom of the window provides a summary of all of the drives shown.
