`static int` | `FAT_SECTOR_BLOCK` Indicates the sector holds a FAT block (0xFFFFFFFD)
`static int` | `LARGER_BIG_BLOCK_SIZE` Some use 4096 bytes
`static POIFSBigBlockSize` | `LARGER_BIG_BLOCK_SIZE_DETAILS`
`static int` | `LARGEST_REGULAR_SECTOR_NUMBER` The highest sector number you're allowed, 0xFFFFFFFA
`static byte[]` | `OOXML_FILE_HEADER` The first 4 bytes of an OOXML file, used in detection
`static int` | `PROPERTY_SIZE` How big a single property is
`static byte[]` | `RAW_XML_FILE_HEADER` The first 5 bytes of a raw XML file, used in detection
`static int` | `SMALL_BLOCK_SIZE` How big a block in the small block stream is.
`static int` | `SMALLER_BIG_BLOCK_SIZE` Most files use 512 bytes as their big block size
