How can you transfer songs from computer to computer using a flash drive

If you are using a Mac, pull the file up from the Macintosh HD and drag it into the flashdrive icon on the desktop. If you are using a PC, pull up the file in Windows Explorer or other searching device, scroll down on the side which is like a little box after you've pulled the file up on the main and bigger box, and locate what drive your flashdrive is (for example, drive H) and drage the file from the bigger box to the smaller box and the appropriate drive in that smaller box.
