How to I delete music files - for Apple users only
This is easily resolved but its an issue that occurs with many Apple users on many different devices and it really is a computer issue, not a Music Player one.
Just by means of explanation ... the Simple Music Player looks and plays all the compatible files it finds on its internal memory regardless of which directory or folder they are in.
The problem arises because Apple iOS doesn't actually delete the files when you press the 'delete' key, but creates a hidden sub-folder called '.trash' or '.trash-1000' and simply moves them into that folder. Whilst you can't see the files, they still exist and so the music player is finding them and playing them.
To resolve the problems you have two choices:
1) empty the .trash folder. There is information how to do this here www.thexlab.com/faqs/trash.html#Anchor-Force-11481 for example.
2) (***** Preferred *****) reformat the Simple Music Player memory card (this will delete everything on the Simple Music Player) and then drag and drop the music you want back onto it again.
How to reformat? The Simple Music Player acts exactly the same as if its a USB stick or flash drive plugged into your machine, so formatting is just the same operation. MAKE SURE YOU REFORMAT USING MSDOS-FAT FORMAT. This is NOT and Apple iOS device so iOS formatting will not work.
There are lots of tutorials on the web (again this is a 'how to operate your computer' problem) - try this one www.pcadvisor.co.uk/how-to/storage/how-format-usb-stick-on-mac-3434423/ and your problems should be solved.
There's a very clear video at youtu.be/ac3jaZ7DjGg if you prefer video help
(PLEASE MAKE SURE YOU ONLY POWER UP THE MUSIC PLAYER ONCE THE USB CABLE IS PLUGGED IN, OR ELSE IT WON'T OPERATE IN USB MODE)
This should resolve your problems
