Description

This structure is used by RARReadHeaderEx function.

Structure fields

• ArcName

  Output parameter, which contains a zero terminated string of the current archive name. May be used to determine the current volume name.

• ArcNameW

  Output parameter, which contains a zero terminated string of the current archive name in Unicode. May be used to determine the current volume name.

• FileName

  Output parameter, which contains a zero terminated string of the file name in OEM (DOS) encoding.

• FileNameW

  Output parameter, which contains a zero terminated string of the file name in Unicode.

• Flags

  Output parameter which contains file flags:

  0x01	File continued from previous volume
  0x02	File continued on next volume
  0x04	File encrypted with password
  0x08	File comment present
  0x10	Previous files data is used (solid flag)

  Bits 7 6 5 (0xE0 mask)

  0 0 0 (0x00)	Dictionary size 64 KB
  0 0 1 (0x20)	Dictionary size 128 KB
  0 1 0 (0x40)	Dictionary size 256 KB
  0 1 1 (0x60)	Dictionary size 512 KB
  1 0 0 (0x80)	Dictionary size 1024 KB
  1 0 1 (0xA0)	Dictionary size 2048 KB
  1 1 0 (0xA0)	Dictionary size 4096 KB
  1 1 1 (0xE0)	Directory record

  Other bits are reserved.

• PackSize

  Output parameter. Lower 32 bits of packed file size. If file is split between volumes, it contains the lower 32 bits of file part size.

• PackSizeHigh

  Output parameter. Higher 32 bits of packed file size. If file is split between volumes, it contains the higher 32 bits of file part size.

• UnpSize

  Output parameter. Lower 32 bits of unpacked file size.

• UnpSizeHigh

  Output parameter. Higher 32 bits of unpacked file size.

• HostOS

  Output parameter. Operating system used to create the archive.

  0	MS DOS
  1	OS/2
  2	Windows
  3	Unix

• FileCRC

  Output parameter, which contains unpacked file CRC32. In case of file parts split between volumes only the last part contains the correct CRC and it is accessible only in RAR_OM_LIST_INCSPLIT listing mode.

• FileTime

  Output parameter. Contains the file modification date and time in standard MS DOS format.

• UnpVer

  Output parameter. RAR version needed to extract file. It is encoded as 10 * Major version + minor version.

• Method

  Output parameter. Packing method.

  0x30	Storing
  0x31	Fastest compression
  0x32	Fast compression
  0x33	Normal compression
  0x34	Good compression
  0x35	Best compression

• FileAttr

  Output parameter. File attributes.
