Greg, are you sure drag and drop doesn't work? Because I just did it. Opened two finder windows, in list view (taking through to the working drive Quicken file and the other over to the backup drive Quicken file) - dragged the file from the main drive to the backup drive and it copied. Both of my drives are internal, but this shouldn't make any difference. I did it from the Quicken backup files (I always back up each time I close the application) which are in my Documents folder.
