FDNPKG is an online update tool for the FreeDOS operating system. It allows to install, remove and update software on a FreeDOS installation using online (http) or local (on disk/cdrom) repositories. It is written by Mateusz Viste for the FreeDOS™ project, but can be used on other DOS systems as well. FDNPKG means "FreeDOS Network Package manager".
GFileSplit is a very simple GNOME app to split a file into fixed size pieces and to join the pieces back into the original file.
In the post-floppy era, this can still be useful because of size limits on mail attachments.
