I don't think 1.0 had a hierarchical filesystem at all did it?  

IIRC, it was basically the same as CP/M 2.2 and had nothing other than a
"root" directory on each floppy [IIRC, CP/M 3.x had some concept of multiple
directories on a floppy but it wasn't a tree structured FS with "paths" --
it was more like partitioning a floppy into multiple drive letters.]

By the time I got my hands on IBM machines 2.x was in common use, so I only
had a brief exposure to 1.x.
