This handy program allows you to see where your disk space is going in an easy to read pie-chart. You select the top directory to scan, and Piechart Disk scans the directory then displays an interactive directory and file list with pie-chart. Since Piechart Disk sorts the directories and files, the largest directories and files are at the top of the list. Click the interactive file and directory list green plus and red minus icons to open and close directories, changing what is displayed in the pie-chart. Right click a directory or file for that entry's detailed information.
