An EGTB is a set of endgames. Each endgame is a set of positions of that endgamethat have similar material. Each position has an integer number which informs how far that position is from mating/being mated or converting, (depends on the type of its metrics). All numbers of an endgame are simply organized as an array of integers. In other words, each item in that array is an integer and mapped to a unique position.

The array can be stored in one or a few files, in none or compressed formats.  The size of an endgame depends on:- The number of involving pieces: more pieces the bigger size- Type of pieces: for standard chess, more Pawns is the smaller size- Type of metric- The largest number: some endgames require only one byte per number/position but some need 2 bytes
