ProDOS on the mighty Apple /// (and also the Apple ][) had a file type metadata back in 1983 :)
In fact even Apple DOS 3.1 (1978) supported 8 different file types.
- jdswain 3y agoIt was called SOS on the Apple ///, originally Sara's Operating System but officially Sophisticated Operating System. It was a very advanced OS for its time, most notably one of the first to include a useful driver model. The SOS filesystem was reused for ProDOS (and later GS/OS as well), but a lot of the advanced features were removed for ProDOS due to wanting to fit into the smaller RAM of the Apple ][.
