Long file names is a typical "I'm boring and have nothing to do" project, so re-invent the wheel... It's basically a DIR command to view the long file names on your floppy disk, while running DOS...
There is no screenshot, and it does not run under ... a lot of windows operating systems... there you can see your long filenames, this was designed for DOS.
Study the sources if you're curious for some low level disc access hacks...
