How do i delete music from my E100?

If you want to delete stuff from your E100 while your actually using it then you go to file manager in the menu, find the file you want to delete and then hold the right arrow until it comes up with 'delete file'. If you want to delete it while your on your computer then find the folder of your E100, find the file and just hit the delete key or right click and 'send to trash' or drag the file to the trash.
