QuikBoot is a simple but effective application which will boot applications and directories. The special thing about it is that it has a Full Recursive feature, in which if you drag a directory to the icon, every single application inside the directory and sub-directories will be booted. Also, directory searching can be stopped by pressing 'space'. A new feature to 1.20 is a settable recurse factor. Basicially, you can now choose how many directory levels you wish QuikBoot to recurse to.
