DiskMapper
"DiskMapper is a remarkable utility that frees up megabytes and megabytes of hard disk space - quickly and easily by showing you a useful, graphical, color-coded map of your hard disk. DiskMapper lets you quickly delete or compress programs and files you dont need or rarely use. Why waste time and money installing a larger drive when you can reclaim the space you need. DiskMapper is more effective than file managers because it finds space wasting files much faster, shows an overview of your drive, and quickly finds large files hidden in deep sub directories. Instead of replacing your hard drive youll save hundreds of dollars, hours of disk drive installation time, and you wont risk your data in the transition to a new drive."
