This page describes the DFF 1.0 file format, an open file format for structured binary data. The DFF 1.0 file format has been superseded by the DFF 3.0 file format.
The DFF 1.0 file format is endian-agnostic: the endianness of all fields is determined by the endianness of the magic number at the beginning of the file.
DFF 1.0 is a very simple format, consisting only of a magic number followed by an array of resource records. No word alignment is used.
| Type | Description | Notes |
|---|---|---|
int32 |
magic |
the magic number 0x25444646; the four-character constant (fcc) %DFF
|
resource[] |
resources |
an array of resource records |
int64 |
type |
the resource type; an eight-character constant (ecc) |
int16 |
id |
the resource id |
int16 |
filler |
should be zero |
int32 |
size |
length of resource data |
byte[] |

An empty DFF 1.0 file consists solely of the magic number.
0000: 25 44 46 46
Or the little-endian version:
0000: 46 46 44 25
