This program is very useful - it helped me find out how much space my directories and files are taking

This product, though a little pricey, is too good to not have. Not only is it really useful and convenient as a pasrt of Explorer itself, it really gives a 'personality' to each folder on the disk... big old files and folders are pale in color and with large size, and are easy to spot.

This software adds folder size information as 3D Pie chart to Explorer itself. Also adds folder size column! Must try
