DupeFinder is a simple application for locating, moving, renaming, and deleting duplicate files in a directory structure. It's perfect both for users who haven't kept their hard drives very well organized and need to do some cleaning to free space, and for users who like to keep lots of backup copies of important data "just in case" something bad should happen.
LD (Logical Desktop) is a program that allows you to do many different things with your computer, but in a consistent way. In LD, you work by composing "actions" made of one verb and one or more objects. The advantage of LD is that you specify verbs and objects in any order, with automatic hiding of the things that don't make sense. The former point enables LD to unify the "task-oriented" and "document-oriented" paradigms. The latter point enables users to compose actions much more easily. Another innovation is that you can browse your filesystem and the Web with a "recently used first" style.
OneFinger is a general-purpose GUI for composing CLI commands with the mouse. Although entirely graphical, it does not attempt to hide the underlying CLI language. It increases your productivity over classical hand-typing by caching commands typed into terminals, which tend to be highly repetitive. Repeated commands can be selected from a list, ordered by last usage time. It includes an integrated file browser that helps you insert filenames without typing them. and allows you to see only those programs that make sense with a given file.
