Introduction

The CLU file type is primarily associated with Lua.

• CLU as a Lua Bytecode Compiled Script:
  These files hold precompiled Lua instructions in a binary format. They run on a Lua interpreter, which reads the bytecode instead of plain text.

• CLU as a Game Data File:
  In some cases (for example in Baldur's Gate) the file stores cluster data for game assets. This type is used by the game engine to organize data. More details are available at D&D Beyond.

• CLU as an Infomap Clustering Output:
  These files are generated by the Infomap tool to group network nodes into clusters. They serve as output data for further analysis. See Infomap for related info.

To open a CLU file, you must know its origin. For Lua bytecode, use a Lua interpreter or decompiler. For game data, the corresponding game engine or mod tools are needed, and for a clustering output, a text editor or analysis software will help view the content.
