Removing Media from Your Phone
Just as you can use File Explorer to copy
media to your phone, you can use it to remove media from your phone. To
do so, follow these steps:
1. Open File Explorer on your Windows desktop and click Computer in the Navigation pane.
2. Double-click Windows Phone.
3. Double-click Phone and then click the folder containing the files you want to remove (Music, in this case).
4. Right-click the file or folder you want to remove.
5. Click the Delete option on the shortcut menu.
