HDFS (see http://www.tardis.ed.ac.uk/~ajcd/beeb/hdfs.html).

HDFS has *format in ROM and the Tube code, is Acorn DFS 1.2 format
compatible, and supports a primitive hierarchical structure. There are some
bits which aren't re-entrant, so you can't *spool the *help from it to disc,
though :-(

It's free, comes with the manual, but since I'm the only person I know who
uses it, there may be bugs lurking away in hidden corners that I didn't use
much.
