WinDirStat is a disk usage statistics viewer and cleanup tool for various versions of Microsoft Windows. Mac OS X users should use Disk Inventory X or GrandPerspective alternatives. Linux users should try KDirStat or others such as Baobab (a component module of gnome-utils package). The program can scan local partitions or entire hard disk drive, presenting the results under a colorful graphical image for used space. It is also a cleanup tool as it allows you to delete files that take much space. The advantage of using this tool is that you can identify files that took the most space and you can also delete them directly from main program interface.
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.
You know the problem: 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.
On start up WinDirStat opens the Select Drives Dialog. Press the OK button.
Then WinDirStat reads in the whole directory tree once (this can last some minutes depending on the hard disk size) and then presents it in three useful views
