XIV Dev Wiki

Character Data Files

Contains information about files that are specific to each character.
Character data is stored in each folder inside the My Games/FINAL FANTASY XIV - A Real Reborn folder. Each character folder is named similarly to FFXIV_CHR0040000001000001, where the portion following the FFXIV_CHR is the character's content ID.

Chat Log

The game writes your chat history to disk each time its internal buffer overflows, which potentially allows you to retrieve chat history in longer play sessions.
