At the end of the day, *most* (not all, but nearly so) of the
*apparent* hierachical fs in current use are simply
human-friendly modes of displaying what are in fact close to
random-ordered collections of blocks - linked, indexed, or some
combination of the above. Not really hierarchical under the covers.
Hierarchical simply doesn't 'map' directly to common physical
storage. Not since torn-tape, anyway.
BTW - what do IBM's 'dotted' file names suggest to you?
All that asidee - hierarchical at-core, or for-display - or NOT
what is needed is a *better* fs. Or several.
FAT is a weak tool by any measure.
JMPO, but Plan9's concept & storage methodology done in Oberon
instead of 'C' would be 'of interest'.
