What does Space Investigator do?

When you run Space Investigator, it analyzes the hard drives you've selected and displays the result in a visual manner in its window.

The left-hand area of the window shows the folders and files your hard drive contains, sorted by size, indicating the relative size of each item in a separate column.

The right-hand area contains the list of the file types that exist on your hard drive, with the legend of the colors assigned to each type for easy identification.

Finally, the bottom part of the window displays the information in a visual manner: each square drawn there represents a file (with the size of the square approximately proportional to the size of the file), and the boxes representing files of the same type are drawn in the same color. This makes it easy to locate the large files that take up the space on your hard drive.

As you move the mouse over the bottom part of the window, the path of the file corresponding to the square under the mouse pointer is displayed in the status bar of the window. If you click on a box, Space Investigator locates the file it represents in the upper parts of the window and selects it there.
