Disk Wave 0.3

DiskWave is a free disk usage utility. It helps you determine what files and folders comsume most of your disk space.
DiskWave was previously known as WhichSize.
The program scans your hard drive to compute the size of all folders and sub folders. The results are stored in memory, which allows faster navigation than the built-in “compute all sizes” option in the Finder. You can easily identify useless directories and delete them.
