AFS is een gedistribueerd bestandssysteem dat oorspronkelijk afkomstig is van de Carnegie Mellon University. Het is vervolgens verder ontwikkeld en uitgegeven door Transarc Corporation, dat halverwege de jaren negentig op zijn beurt door IBM werd overgenomen. In 2000 heeft IBM een opensourceversie van AFS uitgebracht, onder de pakkende naam OpenAFS. Voor meer informatie verwijzen we naar deze pagina. De ontwikkelaars van OpenAFS hebben enkele dagen geleden versie 1.7.8 voor het Windows-platform en versie 1.6.1 prerelease 4 voor alle platforms uitgebracht. De bijbehorende aankondiging ziet er als volgt uit:
