Having trouble with my new 128gb iXpand flash drive

Update from OP…

selecting a a single folder and sending it to my iPad worked.  I had to rename the copied folder with the Artists name, 3 Doors Down, but the mp3s were all there.

this could be a tedious task with so many folders and sub folders …

tried copying a folder with 2 sub folders , the iXpander App just went into a hang mode.

maybe it doesn’t like Alicia Keyes ?

thank you.
