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
I think you are looking for WinDirStat
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.
