The color of the mucus that comes out of your nose when you are sick, whether green, yellow or white, does not necessarily indicate a bacterial infection. An upper respiratory infection typically starts out as a virus, which causes your body to produce excess mucus.
Media Transfer Protocol (MTP) is a protocol with an accompanying set of drivers developed by Microsoft to connect portable devices to a Windows XP PC and synchronize digital media content between those devices and the PC. MTP is geared toward portable devices with hard drives.
MTP works in a different way than USB mass storage devices. USB devices share their entire file directory, exposing even system files and important programs to the computer. MTP exposes only selected files to the computer, meaning that there is no way to alter the system files when in media programs like iTunes.
