DiskChart

Hard disks keep getting bigger and bigger, but somehow we still run out of space. MP3s and other media files are immensely popular-and simply immense. Programs are bigger, and data files are bigger. Windows Explorer isn't much help. It will tell you the size of all selected files in a folder, but nothing about the files in that folder's subfolders. Enter DiskChart, a utility to identify the biggest consumers of disk space.
