Unofficial RISC OS Filetypes List

This version of the file was generated on 2026-03-04 at 02:51:19 UTC and lists all the filetypes that are publicly known, including a number of deprecated ones (and some duplicates).

Updates

The latest version of this list is available from http://foldoc.doc.ic.ac.uk/acorn/doc/filetypes.

Filetype (and module) registrations are now handled by RISCOS Ltd.

Sadly, nobody has time to edit the official filetype list for public consumption. They would have to remove allocations for products which have not been announced to the public yet, hence this list.

Overview

000-0FF	Personal usage (non-distributed)
100-3FF	Non-commercial distributed software
400-9FF	Commercial Software
A00-AFF	Acornsoft and other commercial software
B00-DFF	Commercial software
E00-FFF	Acorn

The minimum requirement for a valid allocation is that double-clicking the file loads an application and does something meaningful with it. Use existing file formats (not just within the Acorn world), and make data interchange as painless as possible. If your software is going to be distributed, get an allocated filetype to avoid clashes.

Key

The list has one line for each different use of a filetype. Each line has the format:

HEX S NAME DESCRIPTION; APP (ORIGIN); APP (ORIGIN).. EXTENSION

HEX Three hexadecimal digits
S Status
- R => This type is registered with Acorn/Pineapple
- D => deprecated - a registered or newer type exists
NAME The short name for the type (File$Type_XXX)
DESCRIPTION The kind of data in files of this type
APP Software which handles this type
ORIGIN The originator (author or company) of the software
EXTENSION Common filename extensions used elsewhere and MIME content types
