Aurender help needed - file loading


hoping some veteran Aurender users can assist.  I have my FLAC library on a USB hard drive.  I'd like to transfer these files to my A15 onto the installed SSD I have connected.  I do not see a path to doing this with my drive connected to the A15.  Am I missing it?  Or is there another way to transfer.

 

thanks for any help
