What are good tools to show disk usage (for Windows)?
How to determine a disk consuming service in Windows 2008 server?

I am troubleshooting performance on a PC with (running Windows 7) whose hard disk is almost full. I am assuming that there is some directory where the user has dumped many large files. On Unix, I would use the 'du' command to determine which directories contributed most to disk usage. How do I accomplish this on Windows? TIA - Frank

Use something like TreeSize Free from JAM Software or WinDirStat which is open source.

I think you are looking for WinDirStat

I have used WinDirStat for years, it gives you a good overview in under a minute. –  Lucky Luke Aug 8 '11 at 15:02

There is the sysinternals du command but you may find something more native like getfoldersize easier to use.

+1 for sysinternals. Even if you don't use du, the other commands make this suite invaluable on a Windows system. –  Bart Silverstrim Aug 8 '11 at 14:51
    
+1 for most exact answer, even if some of the others are easier to use. –  user3490 Aug 6 '13 at 10:43

I'm not aware of any cli tools for checking disk usage. I usually use windirstat to track down what is using my diskspace.

Just to weigh in on GUI tools, I prefer sunburst-style graphs, like Scanner2, to treemaps like WinDirStat; I think they're much easier to read.
