A:
YES!! Absolutely.
I have 58 albums (folders) on one of my USB flash drives. No problem.
I think their is a limit of 100 folders per flash drive. But even 58 Albums, is TON of great music. I customized one of my flash drives, on my Dell computer. I deleted the albums that were not my favorite albums or artists.
So, cab listen to that flash drive for hours & hours, & love everything I hear.
You can do that on the unit itself too, but easier to do on a computer.
I love this player!!
