This program reports the current state of your disks: Total MegaBytes, GigaBytes, the amount of space used and free, and the useable swap space (or memory usage). Furthermore, one can browse through the folder structure with an intuitive pie chart showing relative folder space used.

DiskState can also eliminate space wasted after program crashes or by temporary files no longer needed.

The Duplicate Finder of DiskState uses e.g. a powerful 128-bit MD5 technology to track down redundant files. Even if the file names are different, DiskState identifies duplicates by content and displays duplicates in a comprehensive list.
