Finding Auxiliary File Types

["Brian Haskin" <brian.haskin@a2central.com.remove-11iy-this>]

I am trying to recover some files from a IIe that were written by a person who
recently passed away. The family has no idea how to use the IIe, and they threw
out all the software (a travesty!) before they were referred to me.

I've obtained a ProDOS disk, and ProDOS Filer reports the filetype as $16. This
page ( http://web.pdx.edu/%7Eheiss/technotes/ftyp/ft.about.html ) tells me that
this particular file type belongs to PFS, which is apparently an
office/productivity suite. This file type has multiple auxiliary types, one for
each document type (word processor, spreadsheet, etc.). I need to find the
auxiliary type of the files to determine exactly which PFS program to purchase
(assuming I can find it for sale somewhere), and I haven't been able to find a
way to do it.

So, my question is this: how can I find the auxiliary type of a file on a Apple
IIe?  If there's a way to do it with just ProDOS or Applesoft BASIC, that would
be preferred, but I'm open to trying just about anything.

Many thanks!
