 == History ==
-ZiPatch (.patch) files are a compressed file format for FINAL FANTASY XIV. This file format was later modified in 2012 for DRAGON QUEST X and FINAL FANTASY XIV: A Realm Reborn, which are more similar in their DAT structure to each other than to FINAL FANTASY XIV. As such, many of the block types that are found in this version have been deprecated. Static analysis of the A Realm Reborn executables indicate that they may still be able to read this version.

 == File Header ==
 ZiPatch files have a unique file header (12 bytes), which is used to identify the file format. The ZiPatch File Header is immediately followed by ''n'' blocks, read until EOF, each of which provide ffxivupdater.exe with information to carry out specific instructions.
