HADFS disks have a similar structure to the file structure on Econet
fileservers. Files have public and owner access strings, and directories
can be given user numbers.

Directories can be given a three-byte account number (or user number)
using B*ACCOUNTb. When a directory is logged into with B*I AMb, then its user
number becomes your current user number. When a file or directory is
created, it is given the same user number as the directory it is in. You
cannot do any modification actions in a directory that you do not own, and
any files can only be accessed according to the right-hand (public) access
string. B*MOUNTb sets your user number to the account of the $ directory,
usually 000. B*I AMb to a non-existant directory does the same as B*I AM $b on
the default drive.

Entries can be made private by setting the 'P' option with B*ACCESSb. If an
entry is private, it cannot be seen if you do not own the directory it is
in.

The INFSFronti ROM created by IExtras.NFSFront/si provides OSWORD &14/0
(file-server interface) to simulate a file server and supports the
following functions:

  14: Read disk names
  15: Read users		-> returns a pre-set list
  16: Read date and time	-> returns 00:00:00 on 00/00/1981
  25: Read server version	-> returns NFSFront version string
  26: Read free space		-> returns zero free space
B*OPT2,5b will make OSARGS 0,0 return A=5, so pretending to be NET.

The program INFSTesteri in the IExtrasi directory tests some of the functions.
Any other Econet-type programs will be in directory IExtras.Econeti.
