Visualize Your Disk Space Usage

There are two similar programs that allow you to easily see your what files are taking up most of your disk space. This can be useful when you are running out of disk space and need to decide what to delete.

• The first program is SequoiaView. It uses a visualization technique called cushion treemaps to provide you with a single picture of the entire contents of your hard drive. You can use it to locate those large files that you haven’t accessed in one year, or to quickly locate the largest picture files on your drive.

• The second program is WinDirStat. This program is a disk usage statistics viewer and cleanup tool for Microsoft Windows (all current versions). WinDirStat 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.
