Hi, I can't find in your manual info how to delete files exported to the Loop Transfer folder in iTunes. In the app, I'm told I can create a doc (.wav file) accessible from iTunes. In iTunes, although I can access and download the said files, I can't delete and/or manage them. So, now my iPad is clogged up with old exports, and I don't have a way of deleting them. What do you suggest I should do?
