I just partitioned my single drive so that my system partition is only 40gb, and my "data" partition is the remainder of my 500gb drive. What I would like to do, if possible, is mount this partition on top of my C:\Users folder so that all user data is transparently put into the separate volume. I'm already aware that I can format a volume with NTFS, and then mount it into an empty NTFS folder on a separate volume (instead of assigning it a drive letter, for example), but I don't know how I can go about doing this since the folder I want to use already has data in it. Shame you can do this so easily on linux, but not on Windows.
