Did someone say ICL?
George behaved that way, as did VME, although you could drill down into the file properties further if you knew what sort of file you were looking at.
I recall, in an example of the circularity of life in IT, that we spent a few happy months playing with the prototype Electronic Storage System (ESS), a whole gigabyte of persistent solid state memory mounted as a filestore system that at that time cost £multiple millions (I forget exactly how much, but it was betwen 5 and 10 million). When we formatted the duplexed IDMS database that we dropped on there we got both nodes of 39/80 that we using as our playground.
VME was good like that. A file was a file and did the things that a file did, a directory was a directory and did the things that a directory did, a group was a group and so on and so on. Happy days.
