RXDATA File

What are RXDATA files and how to open them

Are you having problems opening a RXDATA file or are you simply curious about its contents? We're here to explain the properties of these files and provide you with software that can open or handle your RXDATA files.

What is a RXDATA file?

A .RXDATA file is a RPG Maker Data file.

RPG Maker Data files with the .rxdata extension store serialized game data used by RPG Maker XP, a Windows-based tool made by Enterbrain (now part of Kadokawa). They are part of the project "Data" folder inside an RPG Maker XP project. The files define game structure and behavior: actors (character stats), items, maps, enemies, events, system settings, and game scripts. Each project typically includes many .rxdata files (for example Items.rxdata, Scripts.rxdata, Map001.rxdata), each handling a different category of game content.

These files are produced and read by RPG Maker XP. The developer uses the built-in database editors and script editor inside RPG Maker XP to author the content, which is then saved into these .rxdata files. When players run the completed game, the game engine loads them to build the game world. They are not meant to be read or edited directly with simple text editors; modifications generally require the RPG Maker XP software or a third-party tool capable of parsing the file's serialization format.

Internally, .rxdata files are binary serialized Ruby objects; the format is Ruby Marshal version 4.8 (used by Ruby 1.8 in the game's RGSS runtime). Every .rxdata file begins with the two bytes 0x04 0x08 at offset 0, indicating the Marshal version. One particular file, Scripts.rxdata, stores each script's source text compressed using zlib (deflated) inside the serialized object tree.
