I have a new iMac showing up tomorrow...I have been using a MBP connected to an external HD for my Time Machine backup. I also keep all of my media on another external hard drive, clone it to my backup hard drive as well as in the cloud. Is Time Capsule ONLY for Time Machine backups or can you drop/access files from the drive once setup in house. Also, I have an Actiontec Range Extender on my second floor spreading out my FiOS connection from the first floor. Would I still need the range extender? Does it have to connect via hardwire to my FiOS router? Thanks.
