-If intending on using DOSBox_Pure, ''.zip'' files can be renamed to ''.dosz'' (FIXME for fun? Why can you do this? Is it needed in Batocera?) In addition, to mount a ZIP file as the virtual ''A:'' or ''D:'' drive the ''.zip'' file can be renamed to ''.d.zip''.+If intending on using DOSBox_Pure, ''.zip'' files can be renamed to ''.dosz'' (It is a relict from the libretro frontend that wants to load the content of ''.ZIP'' files instead of sending it to DOSBox Pure to load. This was especially useful for CD images in ZIP format which RetroArch refuses to append through its Disc Control menu. So for fun? ... FIXME - yes it is rather a joke because BATOCERA is an advanced launcher where each system is separated and a dependency to a file suffix does not exists).
