How to Open AFF Files

The File extension aff is used by the following file type(s):

type 1 description:
Acorn vector draw files
AFF files suffix is associated with Acorn/Risc OS graphic application Draw. File contains draw similar to Windows WMF and SVG vector-based format.

Extensions used to map this file come in two varieties. The first is a word describing the file – in this case “.draw” which is “.drw” in the 8.3 parlance.

The second way of mapping the file is to use a literal form of the RISC OS filetype system. In this, three bytes provide a range of possible file types from &000 to &FFF (there are no extensions, just “type” metadata).

In this case, Acorn DrawFiles would be given the extension “.aff” because the file is type &AFF, or 0xAFF, $HAFF.
