I am having a problem with the C partition of my sbs 2008 box.
Windows is claiming that there is only 280 mb left, causing untold problems with the server.
However, when I look at all the dir's, (including hidden and system) it only accounts for half the drive.
I ran WinDirStat on the drive and it is saying there is a 20 gb 'unknown' file.
How do I figure out if this file is important, and then clean it up?
