JStart gives the ability to start Java class files (or applets) by double clicking on them from the desktop like any executable program. You only have to assign *.class files to this program. It loads a class file, investigates it according to the Java Sun class file specification, extracts the full class name (including packages), and invokes the main method of that class.
PyFile is a graphical file browser written in pygame (Python/SDL). It features all common file browser options as well as additional functions like regular expression filtering, directory bookmarking, etc. In opposition to the other available file browsers, PyFile makes heavy use of graphics to give you a nice working area with lots of effects. Every single aspect of PyFile is configurable to your needs and you can even easily extend PyFile with your own Python scripts.
ThreeDFM is a 3D file manager that uses OpenGL. Currently, only file system browsing is implemented. The main reason for this project is that using a 2D file manager is slow. More information about files can be conveyed in 3 dimensions. Not only will you be able to see the file's properties, but you will quickly be able to see a particular file's relationship to the others in the surrounding directories. A simple example of this is the file's size, as this can be shown by the size or colour of its representation. It will also be possible to view the contents of multiple directories simultaneously as they stretch off into the distance.
FileLister is a filesystem indexing tool with a Web based frontend. Running platformindependently in a Web environment, its goal is to easily find files in large archives, using a rich set of search configuration options. Additionally, you may download single files or even create and download zip files on the fly from the results of your search.
ded, the directory editor, allows you to navigate multiple file lists or a directory tree, viewing or changing file attributes rapidly. In addition to conventional file information, it operates on files' RCS or SCCS archives, making it useful for source control as well as system administration. It is curses-based.
