My hard drive on my MBP is becoming full. I currently have my Aperture 3 files referenced on this internal drive. I am thinking about moving these referenced to an external drive. If this external drive is plugged in via USB to my Time Capsule will this work as if plugged in directly to my MBP? Will the files be editable etc as normal? Can I back up this external drive that is plugged into the Time Capsule back to the Time Capsule using Time Machine? Thanks.
