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
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]
