When we want to know whether the file is in U disk or the remaining space is adequate, is it necessary to connect U disk to the computer?
The answer is no. This U disk contains the built-in battery to provide power.When U disk is connected to a computer ,battery will be charged
automatically. When we do not have a computer at hand ,we just need to turn on the switch,then slide the touch screen ,then browse the files.
Second we can get the size of remaining space through the display bar of U disk . The red bar represents the used space, and the blue bar represents the remaining space.
