music dot under bar (._) files
I have a reasonably large music library in Apple Music on an iMac. I have tried to copy the music files to an USB drive to plug into my blue ray play to allow me to play music through my home theater system. To create the USB drive I simply went to the iTunes folder with all of the music files using Finder, highlighted the artist folders that I wanted to copy, and pasted them to the Western Digital drive. I have used this same process to copy the music to a USB thumb drive to play in my car. When I plug either the USB drive or USB thumb drive into my Sony ES1100UHD player they both show that either the file is corrupt or unsupported. The display with the prefix ._ (dot under bar) on the display connected to the blue ray player. Interestingly, when I take the same USB thumb drive and plug it into my vehicle (2018 Chevrolet Colorado) the ._ files do not appear and the music plays with no problem.
Any ideas on how to get the files to play through the Sony ES1100UHD blue ray player will be greatly appreciated.
Thank you.
