WinDirStat - What happened to all my disk space?

WinDirStat is the answer.
Another one of those freeware programs that has been around forever, but always comes in handy.

Shows where all your disk space has gone and helps you clean it up.
On start up, it reads the whole directory tree once and then presents it in three useful views:
  • The directory list, which resembles the tree view of the Windows Explorer but is sorted by file/subtree size,
  • The treemap, which shows the whole contents of the directory tree straight away,
  • The extension list, which serves as a legend and shows statistics about the file types.
