Transfer music Add music to your phone ANDROID TIPS
Go to www.android.com/filetransfer/ and download the Android File Transfer app. Now follow the standard installation process for your desktop or laptop and leave it closed.
The software will open automatically as soon as you connect your phone to your desktop via USB and present a familiar-looking file manager window. There are no graphical areas – it is designed purely for functionality and should be obvious to most people straight away. You can now simply drag and drop music files from another file manager window to the Music folder within the main Android File Transfer window. To keep albums and artist information intact, make sure you drag the entire folders, but each transfer should still only take seconds to complete.
