 ====== Zone File System ======
-The //Zone File System// is a method used by //Star Trek: Armada// to store game assets in archive-like files, namely the //objtxt.zfs// and //assets.zfs//. Especially the latter contains most of the [[en:games:star_trek_armada_1:modding:ODF files]] as well as the [[en:games:star_trek_armada_1:modding:tech_tree_file|tech tree files]]. The contents are not stored in their plain format, so the whole storage method may be considered kind of a method of obfuscation of actual game assets. The format is, however not very complicated to decipher/unpack.

 ===== ZFS File Format =====
 A ZFS has a header as well as directory-like sections and actual file content sections.
@@ Line 6: / Line 6: @@
 The header has a length of 28 byte, consisting of the following information:
 ^  Start Offset  ^  Data Type  ^  Meaning  ^
-| 0 | uint32 | ID of the File, usually ''ZFSF'' |
+| 0 | uint32 | ID of the File, Usually ''ZFSF'' |

 If the //Next Directory Block Offset// is zero it implies that no more directory blocks follow, marking the block the last one of the directory.

+==== Encryption/File Contents ====
+The file content itself is not stored in plain in the ZFS files, while the file names and metadata of directories are. The >>encryption<< of the file contents is actually very simple: Each file is stored in chunks of 4 bytes, each being xor-ed with the //Cypher Key// taken from the header. So in essence the >>password<< is provided along with the encrypted file contents. This is why this method of storage cannot seriously be considered proper encryption. Neither is the algorithm strong, nor is an already provided password any serious blockage from reading the file. It's at best a method of obfuscating things.
