I want to rename and customize my audio files for easier acess and because they are incorrect artists stated on the audio files.I "right click" on my"mouse" and select the topic "rename".I procede to delete unwanted characters (letters,numbers) that I don't want and add characters (letters,numbers) that I do want.When I obtain the desired renamed name I want to name the audio file,I click "enter" on the keyboard and the old file name reappears.How do I get my changes to stay????
