It should be relatively simple to transfer music stored on your computer onto a USB flash drive. As long as you know where your music is stored on your computer, then it should be a simple case of copying and pasting the music files onto the USB drive once you have plugged it in.
If you are using a computer with the Windows operating system, then you can take the following steps:
Plug the USB flash drive into one of the empty USB ports in your computer.
Open Windows Explorer. The USB drive should appear on 'My Computer' as the E drive. It may be referred to as a 'Removable Drive' or you may already have given it a different name.
The USB drive should appear on 'My Computer' as the E drive.
Open another Windows Explorer window and locate where you store all of the music files on your computer that you want to transfer
Right-click on the music/video files you want and select 'Copy'
Return to the window containing the USB drive and select 'Paste'
Repeat these steps until all the music you want to transfer has been dropped into the USB flash drive folder.
Once you have done this and you want to remove the USB drive from your computer, make sure that you select the 'Safely Remove Hardware' or 'Eject' option to ensure that the data on the drive are not corrupted or lost.
