![]() ![]() Size of header data starting from Header type field We use 0x prefix to define hexadecimal values, such as 0xf000 General archive structure General archive block format FieldĬRC32 of header data starting from Header size fieldĪnd up to and including the optional extra area. byte, uint16, uint32, uint64īyte, 16-, 32-, 64- bit unsigned integer in little endian format. Which means 0 with continuation flag set. Necessary and then fill several leading bytes with 0x80 hexadecimal, In such situation it can allocate more space than really Sometimes RAR needs to pre-allocate space for vint before knowing This value may be increased in the future Second byte, if present, contains next 7 bitsĬurrently RAR format uses vint to store up to 64 bit integers, ![]() So first byte contains 7 least significant bits of integerĪnd continuation flag. If highest bit is 0, this is the last byte Can include one or more bytes, where lowerħ bits of every byte contain integer data and highest bit in every byte Information on data structures, please use UnRAR source code. If you need information about algorithms or more detailed Here we describe basic data structures of archive format introduced RAR 5.0 archive format RAR 5.0 archive format ![]()
