WinDirStat : Window Directory Statistics

Just installed WinDirStat.

It basically shows where all your disk space has gone...

When the hard disk is almost full, and you don't know, where the big files actually are lying, which occupy all the space. They may well be hidden in sub-sub-directories. To find out this by means of the Windows Explorer, is tiring: you would have to expand and collapse directories over and over or view the "Properties" of the directories, which always count just the size of a single subtree. It's hard to form a mental image of the hard disk usage in this way. This is where WinDirStat helps.

Several "clean up" actions can be applied to a selected item.
