- --------f-RIFF------------------------------
-
- The RIFF (Resource interchange file format) format was created by
- Microsoft and is used by many applications like Windows, Corel Draw
- etc.. It is block structured, each block has a header ID and a size, so
- that even a program that works with an old version of the file format
- can skip the unknown parts of the file and work on the known parts of
- the file. All RIFF blocks begin on a word boundary so it might be
- necessary to skip an additional byte. In the present specification, only
- one RIFF block per file is allowed, and only the RIFF and LIST blocks
- may contain subblocks.
-
- The order of blocks in a RIFF file is not mandatory, so you should
- always scan the whole file for the block ID you seek. Throughout this
- file, the RIFF block IDs are given in square brackets []. Each ID is
- always 4 characters dword.
-
- OFFSET Count TYPE Description
- 0000h 4 char ID='RIFF'
- Each RIFF format file has a header with the
- signature and the size of the following
- blocks.
- 0004h 1 dword Block size. This size is the size of the block
- controlled by the RIFF header. Normally this
- equals the file size.
- ="BSZ"
- 0008h 4 char Format name. This is the format name of the RIFF
- file.
- After this RIFF header comes the first RIFF record. Each RIFF record has the
- following format :
- OFFSET Count TYPE Description
- 0000h 4 char Signature. This is the description of what is
- contained in this block.
- 0004h 1 dword Block size. This is the size of the following
- data block. To get the offset of the next RIFF
- block record, you have to add this value + 8 to
- the offset of the current record.
-
- ---RiffBLOCK [LIST]
-
- This block contains a string list, again in the RIFF subblock format.
- This list is used for messages and/or copyright messages. All strings in
- the LIST block share the same format, each block contains one ASCIIZ
- string - the most common LIST block is the [INFO] block, which can
- contain the following subblocks :
-
- [INAM]
- The name of the data stored in the file
- [ICRD]
- Creation date of the file
