Region File Format
Concept: The minimum unit of storage on hard drives is 4KB. 90% of Minecraft
chunks are smaller than 4KB. 99% are smaller than 8KB. Write a simple
container to store chunks in single files in runs of 4KB sectors.
Each region file represents a 32x32 group of chunks. The conversion from
chunk number to region number is floor(coord / 32): a chunk at (30, -3)
would be in region (0, -1), and one at (70, -30) would be at (3, -1).
Region files are named "r.x.z.data", where x and z are the region coordinates.
A region file begins with a 4KB header that describes where chunks are stored
in the file. A 4-byte big-endian integer represents sector offsets and sector
counts. The chunk offset for a chunk (x, z) begins at byte 4*(x+z*32) in the
file. The bottom byte of the chunk offset indicates the number of sectors the
chunk takes up, and the top 3 bytes represent the sector number of the chunk.
Given a chunk offset o, the chunk data begins at byte 4096*(o/256) and takes up
at most 4096*(o%256) bytes. A chunk cannot exceed 1MB in size. If a chunk
offset is 0, the corresponding chunk is not stored in the region file.
Chunk data begins with a 4-byte big-endian integer representing the chunk data
length in bytes, not counting the length field. The length must be smaller than
4096 times the number of sectors. The next byte is a version field, to allow
backwards-compatible updates to how chunks are encoded.
A version of 1 represents a gzipped NBT file. The gzipped data is the chunk
length - 1.
A version of 2 represents a deflated (zlib compressed) NBT file. The deflated
data is the chunk length - 1.
