What to do with .AppleDouble folders.
I want to backup most of the data on my MyBookLive to my old MyBookWorld (blue ring). Previously I’d copied from MBW to MBL so I have most of the data on both already which should save some time in doing a full backup. BUT when compare the data the MBL has lots of .AppleDouble folders while the MBW does not. Should I worry about these? Should I back up the .AppleDouble from the MBL to MBW? Or should I delete them all?
