Unknown Files Taking Up Hard Drive Space

[voodoochild16]

What does Windows Explorer show as free space? Is the drive actually partitioned into 1 250gb chunk? What does Disk Management show? (if you don't know where it is, just search for Disk Management under the Windows 7 start button, it'll say "Create and format hard disk partitions", or just do start/run/diskmgmt.msc)

Here is the screenshot of my C drive showing that I only have 28GB's left on that drive: http://postimage.org/image/wxsvolmc3/

Normally I would make the images viewable on this thread without having to click a link, but i couldnt upload them directly so I had to go to a site and link them and then post them here. Thank you all for all the suggestions so far.
