._ shows at the beginning of songs on an SD card for music in my car
I've added content to an SD card from iTunes and use it to play music in my car. When I go to play the songs the songs are listed with a ._ in front of the song name and when I click on the song to play it says invalid and scrolls through the list greying them out until the original song I added shows up normally and it plays. More annoying than anything.
Are the ._ files album artwork and how do I fix this issue?
Thanks,
Gavin
