I only ever heard it called the ProDOS file system. I don't see any 
specific name given in my copy of the ProDOS 8 Technical Reference 
Manual.

The first Mac file system was MFS. M for Macintosh. Completely flat file 
system with an illusion of hierarchy maintained by the UI.

In 1985 (System 3.2, IIRC) they introduced HFS. H for hierarchical. 
Introduced a few other benefits, but also some new restrictions. 
Probably the most annoying is that the maximum length of a file name was 
cut in half.

Mac OS 8.1 brought HFS+. A whole raft of new features in the file 
system, many of which weren't actually leveraged by the OS immediately. 
The biggest benefit for most people was probably that they raised the 
upper limit on the number of allocation blocks, which meant no more 
half-meg grocery lists on large volumes. Some of them, in fact, only 
used in the last couple of years.

I have no idea what it means, but it's such a cool "word" (by which I mean
pronouncable sequence of letters) regardless.
