Hi
You have to have the correct category SELECTED first, then browse the folders, and you will see they are there.
eg. If you are searching Registration Files: Press Registration, then browse folders. If Voice, or Pads, select from their button, then browse to find/select.
If you are searching/selecting Midi Files, Press the SONG entry, then again browse to the folder!
I had this temporary mental block when I started with T5 😂👍🎹
