In reading up on the Time Capsule, it can be used as a router and for storage purposes. Some questions: 1) can the Time Capsule be used just as an external hard drive, not for back up purposes at all? Is there a setting that needs to be checked to make sure that it doesnt back up anything at all. 2) can I move files from a macbook or pc to the time capsule via an ethernet cable for faster speeds? Do I need a special ethernet cable? 3) can I also move files from a macbook or pc to the time capsule via wifi if I want, just wondering if it is possible?
