The Mount Tray application is used to facilitate the mounting and unmounting of USB storage devices. It is included in Control Panel and as an icon in the system tray, meaning that in can be used within any window manager, even those that do not provide a USB mounting utility. It can also be started by typing pc-mounttray &.
If you connect a USB drive, a pop-up message will indicate that a new device has been detected. Right-click the Mount Tray icon to see a screen similar to Figure 8.10a.
Figure 8.10a: Mount Tray After a USB Device Inserted
In this example, an external USB hard drive was inserted while logged into the KDE desktop and detected as "USB-Device-0". The mouse was hovered over that directory in order to see the two possible actions: to "Mount da0s1d" which makes the drive accessible for this login session or to "Auto-mount" which will both make the drive accessible for this login session and automatically make the drive accessible the next time it is plugged in. If you click either option, a pop-up message will indicate that the drive is mounted. If the desktop has a default file manager, it will open with the contents of the device displayed. In this example, the dolphin file manager opens as it is the default KDE file manager. If the desktop does not provide a default file manager, Mount Tray will provide an "open with" dialogue so that you can select the utility to use to browse the contents of the USB device. A list of available file managers can be found here.
