This is a really good example of the simplest archive format possible. * N1 U( G" ^) t) z) Y6 Y
" }' Y- P9 l+ M$ A8 w% p% z/ l- S/ l. O
The archive begins with a 4 byte signature 'PFPK'.
$ H' X) b9 R, t, ]; E& zImmediately after that is an 32 bit integer telling you how many files are in the archive. 4 y2 V/ c1 Y) x' U# B; y2 m
. B* ~( ^. O7 ~6 sThen it starts the file allocation table.
7 i5 h. ?/ H N9 P/ W$ ]Each entry consists of:
+ [0 T C2 a$ gByte - Number of characters in the file's name.
1 n; C; g/ C9 L# y9 E9 LString - File name.
9 t: x, A* h6 [Int32 - Address of the beginning of the file. # q2 \3 S* _. I% @) C: E
Int32 - Length of file in bytes.
% D4 L9 P: x" Z
8 z3 f1 k: U3 YNo encryption. No compression. Quite boring actually.
8 ]; Y2 B9 H7 X* u3 uThis format should be a required task for an absolute newbie as an introduction to writing archive unpacking software. 1 u7 _3 S+ J d6 W2 P* U

这个格式除了梦之旅3，还在很多游戏中有运用。
