I've never even heard of .pl files and I've been downloading files from Audible for five years now. When I go to My Library, I don't see a file extension at all--I just see the book titles, a combo box to choose the format (format 4 is my default), and a download button. After I've downloaded the file, it has an .aa file extension. ----- Original Message ----- From: "Rick Fox" <richardfox1@xxxxxxxxxxx> To: <bookport@xxxxxxxxxxxxx> Sent: Monday, July 31, 2006 10:46 AM Subject: [bookport] Re: Audible.com problems HI Walt and other list members, Walt, can you download .aa files from your "my library" page? If so, how. I can only see .pl files. Rick Fox
