List of RISC OS filetypes

This is a sub-article to RISC OS.

RISC OS filetypes use metadata to distinguish file formats. Some common file formats from other systems are mapped to filetypes by the MimeMap module.^[1] Such mapping was previously handled by DosMap.^[1]

The MimeMap module maps RISC OS filetypes to and from MIME content types, dotted filename extensions and Apple's Uniform Type Identifiers.^[2]^[3]

Requests for new filetype allocations for all RISC OS versions are handled centrally by RISC OS Open.^[4]

RISC OS filetypes

Filetypes were originally classified by Acorn into distinct ranges:

Hexadecimal range		Designation	Use
Start	End	Designation	Use
000	0FF	User	Unallocated^[5]
100	3FF	Non-commercial software	Allocated^[5]
400	9FF	Commercial software	Allocated^[5]
A00	AFF	Acorn	Reserved^[5]
B00	DFF	Commercial software	Allocated^[5]
E00	FFF	Generic data	Allocated^[5]

User

This range of filetypes was intended for personal use in closed systems, not for general distribution. Nevertheless, many programs using these types were distributed, especially as Public-domain software. Consequently there are many clashes.
