Have you ever run out of disk space, and then wondered where all the big files were that you needed to delete? In Windows you have the fun task of right-clicking on every directory to get its size, and then repeating the procedure on all its subdirectories. On Unix, you end up doing `du -csh *` or `du -cs | sort -n` in every directory. This program simply displays a directory tree sorted by size and lets you mark files and directories to delete. This way all your big directories are at the top, and easy to find.
