I connected smartphone to computer (windows vista computer) using usb cable. When turned on the phone, I could find the device showed the same folders and subfolders as when viewed directly on the device. I'm not sure that this is normal. The folders and subfolders must have some contents, but none is shown whether through the device or through the computer. The device itself showed that usb connection to computer was made, as well as the computer' file explorer showing the set of folders from the device. I must be missing some kinds of settings or options. I know at least that the phone itself contains a few Contacts of people & telephone numbers, but I could not find any such files or contents in the folders.

Device: Alcatel Onetouch Smartphone A463BG, Android 4.4.2
