I copied my NLS books folder to my Seagate external USB drive. Now that I have read one of the books I want to delete it from the Seagate drive. I found it and pressed command delete and got a message saying preparing filename for deletion. After about an hour and no progress I aborted the deletion with quite a bit of trouble doing so. Because I had so much trouble with it I don't want to go back and try it again until hearing from someone on this list. Is there something I should do other than just find the book and press command delete? Any help will be appreciated.
