This file contains ambiguous Unicode characters

This file contains Unicode characters that might be confused with other characters. If you think that this is intentional, you can safely ignore this warning. Use the Escape button to reveal them.

Each block:

HEAD_CRC       2 bytes     CRC of total block or block part
HEAD_TYPE      1 byte      Block type
HEAD_FLAGS     2 bytes     Block flags
HEAD_SIZE      2 bytes     Block size
ADD_SIZE       4 bytes     Optional field – added block size

Field ADD_SIZE present only if (HEAD_FLAGS & 0×8000) != 0

Blocksize:

if (HEAD_FLAGS & 0×8000) == 0  && HEAD_SIZE+ADD_SIZE 
	if the field ADD_SIZE is present – when
(HEAD_FLAGS & 0×8000) != 0.

Types of blocks

HEAD_TYPE=0×72          marker block # first block
	The marker block is actually considered as a fixed byte
	sequence: 0×52 0×61 0×72 0×21 0x1a 0×07 0×00
HEAD_TYPE=0×73          archive header
	
HEAD_TYPE=0×74          file header
HEAD_TYPE=0×75          old style comment header
HEAD_TYPE=0×76          old style authenticity information
HEAD_TYPE=0×77          old style subblock
HEAD_TYPE=0×78          old style recovery record
HEAD_TYPE=0×79          old style authenticity information
HEAD_TYPE=0x7a          subblock



HEAD_FLAGS:
0×0001  – Volume attribute (archive volume)
0×0002  – Has comment (v3 uses the separate comment block and does not use this)
0×0004  – Archive lock attribute
0×0008  – Solid attribute (solid archive)
0×0010  – New volume naming scheme (‘volname.partN.rar’)
0×0020  – Authenticity information present RAR 3.x does not set this flag.
0×0040  – Recovery record present
0×0080  – Block headers are encrypted
0×0100  – First volume (set only by RAR 3.0 and later)
0×4000 – if set, older RAR versions will ignore the block
0x8000 - if set, ADD_SIZE is present and bs = HEAD_SIZE + ADD_SIZE
