Rich wants to know how to transfer large files like audio books. Leo says that audio books aren't that big. But Rich still wants to know how he can he securely transfer them to his publisher without them being corrupted or pirated. Leo says that's a common issue. He shouldn't attach it in an email. Rich should send a link to the file that's located on a drive like Google Drive, ShareFile, or DropBox. DropBox is very secure and he can encrypt the files before uploading them. Zip would allow him to password encrypt it. He could also store it himself on his own server with something like the File Transporter.
