Currently, I have my time capsule set up as an external hdd/NAS. Got a document folder, videos, music, etc. I know time machine is a backup, but how does it work filesystem-wise? If I go into my time capsule on a finder window, how will I see my backups? As a partition? Folder? Backup file? Will my other files on the time capsule remain intact? Can I still access/move/copy/cut/edit my files? Or does time capsule monopolize the device as a backup-only system?
